Similar, alcohol abuse induced a significant reduction in testosterone, LH, and FSH levels in adolescent boys (Diamond et al. ; Bree, M.P. 1998) by alcohol exposure. Taken together, these findings clearly show that the activities of the HPG and GH/IGF-1 axes during puberty are closely interconnected. Endocrinology 128(3):14041408, 1991. For example, these individuals consistently exhibit a reduced or absent response of TSH to TRH (Sellman and Joyce 1992). This binding decreases CRF, AVP, and ACTH production (figure 1). 2005). Macrophages residing in the brain (i.e., microglia) play an important role in these neurotoxic effects of alcohol (Boyadjieva and Sarkar 2010; Fernandez-Lizarbe et al. Alcoholism: Clinical and Experimental Research 39(9):16651670, 2015. Neutralization of circulating CRF using specific antibodies inhibited ethanols stimulatory actions on ACTH and corticosterone secretion (Rivier and Lee 1996). In addition, ethanol exposure increased the mRNA levels for several methylating enzymes and enzymes called histone deacetylases that modify the proteins (i.e., histones) around which the DNA is wound, which also interfere with transcription (Gangisetty et al. 2015; Herman 2002). Alcohol reaches your brain in only five minutes, and starts to affect you within 10 minutes. Research has shown that alcohol can activate the hypothalamic-pituitary-adrenal (HPA) axis, which is likely the reason for the relaxing effect of alcohol.

PMID: 22302180, Nagy, L.E. ; Krampe, H.; et al. 2014). However, more studies are needed to help with our understanding of the adipose tissue pathology associated with alcohol abuse. PMID: 21892982, Haas, S.L. Moreover, recent studies have demonstrated that peripheral administration of oxytocin can reduce ethanol consumption in rats (MacFadyen et al. Life Sciences 43(16):13251330, 1988. Currents in Alcoholism 8:359378,1981. In a stressful situation, a brain region called the amygdala sends out a stress signal to the hypothalamus, which induces the activation of the sympathetic nervous system and the release of the neurotransmitter acetylcholine from preganglionic sympathetic nerves. PMID: 6443069, Gangisetty, O.; Wynne, O.; Jabbar, S.; et al. All these different parts of our brain are the core reasoning behind nearly all of our actions. PMID: 10397281, Sarnyai, Z.; Shaham, Y.; and Heinrichs, S.C. Effects on pubertal hormones by ethanol abuse in adolescents. Common manifestations of hyperprolactinemia in women include lack of menstrual cycles (i.e., amenorrhea) and excessive or spontaneous secretion of milk (i.e., galactorrhea). After a couple of years of sobriety, this functioning returns to normal.. Powered by WordPress / Academica WordPress Theme by WPZOOM. Arhiv za Higijenu Rada i Toksikologiju 64(2):5160, 2013. . Metabolism 44(12):15771580, 1995. In the testes, in contrast, LH stimulates testosterone production and release, whereas FSH controls spermatogenesis. Alcohol and Alcoholism 39(4):281286, 2004. Chronic ethanol-induced insulin resistance is associated with macrophage infiltration into adipose tissue and altered expression of adipocytokines. 2000). In addition to its effects on peripheral tissues, such as adipose tissue and the liver, where it induces insulin resistance, heavy drinking also negatively affects pancreatic -cell function. PMID: 18191055, Beulens, J.W. The hippocampus plays a major role within the brain of human beings and other vertebrates. Alcohols deleterious effects on the endocrine system have far-reaching consequences that can result in serious physiological and behavioral disorders. If you or a loved one are suffering from addiction, it is vital to be aware of these possibilities to make an informed decision moving forward. Proceedings of the National Academy of Sciences of the United States of America 97(5):23372342, 2000. When alcohol reaches the hippocampus, a person may have trouble remembering something he or she just learned, such as a name or a phone number. Overdosing on alcohol often follows blackouts, which can be dangerous and even lethal. Clinical Endocrinology (Oxford) 55(1):4146, 2001. Whether it be group counseling in a rehabilitation center or attending weekly Alcoholics Anonymous (AA) meetings, having a place to find camaraderie is crucial. In order to affect cognitive functions such as learning and memory alcohol must first enter the brain. In human placental tissue, although ex vivo alcohol administration (less or more than 72 g/day) did not affect the rate of aromatization, in vitro incubation of choriocarcinoma cells with 5-50 mM of alcohol increased estradiol secretion, which could be due to increased aromatization. Alcohol, intestinal bacterial growth, intestinal permeability to endotoxin, and medical consequences: Summary of a symposium. Unlike other cells within the human body, brain cells do not regenerate. Other hormones from the adrenal glands and the pituitary gland back up the function of glucagon to make sure the body's glucose level doesn't fall low enough to cause fainting, passing out or even brain damage. Because rehabilitation and detoxification come in many different forms, finding a place that aligns with your recovery goals and desired outcome is important. Numerous studies have documented alcohols diverse deleterious effects on the HPG axis and its hormones (figure 2). The hippocampus is a structure that is vital to learning and the formation of memory. ; et al. Regulation of testicular function in the stallion: An intricate network of endocrine, paracrine and autocrine systems. Alcohol, inflammation and gut-liver-brain interactions in tissue damage and disease development. PMID: 8265735, de Wied, D.; Diamant, M.; and Fodor, M. Central nervous system effects of the neurohypophyseal hormones and related peptides. PMID: 8861280, Roser, J.F. For example, men with AUD exhibited impairments both in the serotonin-mediated stimulation of GH secretion (Coiro and Vescovi 1995) and in melatonins effect on basal and hypoglycemia-induced GH secretion (Coiro and Vescovi 1998) during early abstinence. 1998) and rodents (Emanuele et al. Human studies have documented that moderate alcohol consumption induces disruptions in normal hormone levels during puberty, including a decrease in estrogen levels in adolescent girls that was sustained for long periods of time (Block et al. A prospective population-based study of alcohol use and non-insulin-dependent diabetes mellitus. 2023 Dotdash Media, Inc. All rights reserved. The .gov means its official. 1990), and kisspeptins (Navarro et al. Zimmermann, U.; Spring, K.; Kunz-Ebrecht, S.R. ; et al. Journal of Neuroendocrinology 3(1):19, 1991. Endocrine Reviews 30(2):152177, 2009. High circulating TNF levels, in turn, have been implicated in the development of peripheral insulin resistance (Hotamisligil et al. Biology of Reproduction 28(5):10661070, 1983. Moderate alcohol use may have protective effects by enhancing peripheral insulin sensitivity (Conigrave et al. 1993; Holbrook et al. This effect was associated with a significant decline in circulating IGF-1, LH, and estrogen and was most pronounced at 32 months of age. In addition, the knockout mice exhibited a reduced sensitivity to the locomotor-stimulant and rewarding effects of ethanol (Olive et al. PMID: 2239905, Hotamisligil, G.S. Two of these permanent problems include Wernickes Korsakoff Syndrome and Hepatic Encephalopathy. PMID: 1330488, Emanuele, N.V.; LaPaglia, N.; Steiner, J.; et al. ; Tentler, J.J.; Kirsteins, L.; et al. These findings clearly indicate that chronic alcohol exposure induces a -cell dysfunction and not an enteroinsular incretin dysfunction, because the decrease in insulin response compared with the control group also was observed when glucose was administered intravenously. This could account at least for part of the alcohol-induced impairment in -cell function, because activation of GABA receptors in pancreatic -cells increases insulin secretion (Bansal et al. Additional studies of chronic alcohol administration found an association between HPA axis response and level of alcohol consumption (Richardson et al. Circulation 102(11):12961301, 2000. Note that liver failure has to occur first before this disorder becomes symptomatic. Anatomical Record 202(2):255260, 1982. It may be why that glass of red wine or vodka soda often causes you to crave munchies. Psychoneuroendocrinology 8(3):259275, 1983. ; et al. PMID: 6755122, Coiro, V., and Vescovi, P.P. PMID: 8590623, Mason, G.A. 2013). The brain consists of several sections controlling different aspects of what makes you human. Due to its small size alcohol in the blood can passively diffuse (through the blood brain barrier) into the brain. One of the ways in which alcohol can damage the hippocampus is by disrupting neurogenesis. Diabetes Care 27(5):1240, 2004. PMID: 18330713, Dong, H.; Kumar, M.; Zhang, Y.; et al. PMID: 25913220, Sarkar, D.K., and Fink, G. Mechanism of the first spontaneous gonadotrophin surge and that induced by pregnant mare serum and effects of neonatal androgen in rats. Verywell Mind articles are reviewed by board-certified physicians and mental healthcare professionals. The cause of the alcoholic gait is brain damage called alcoholic cerebellar ataxia.

When alcohol reaches the hippocampus it decreases the electrical activity of neurons by binding to specialized proteins (or receptors) that are embedded in the neuronal membrane. The reduced hormone levels affected the monthly pattern of menstruation in the rhesus macaques and induced a lengthening of the intervals between menses in the alcohol-exposed monkeys (Dees et al. ; and Symmes, S.K. PMID: 8373011, Vescovi, P.P., and Coiro, V. Effect of diazepam on growth hormone secretion in abstinent alcoholic men. Since the discovery of leptin (Zhang et al. PMID: 18436706, Haorah, J.; Ramirez, S.H. But serotonin and glutamate levels drop the more you drink, and as you consume more it can leave you feeling depressed. At this point of consumption, the user can be described as someone who is acting on animal instincts since all parts of the brain that regulate human reasoning have gone offline. Cyclic variation of oxytocin in the blood of pituitary portal vessels of rats. Chronic ethanol consumption induces the production of tumor necrosis factor-alpha and related cytokines in liver and adipose tissue. An inability to remember the entire event is common when a person drinks 5 or more drinks in a single sitting (binge). PMID: 7832470, Hoffman, P.L., and Tabakoff, B. Centrally acting peptides and tolerance to ethanol. Furthermore, in a study of 4,649 healthy individuals who were exposed to increasing levels of alcohol, Knudsen and colleagues (2001) found an association between a reduced thyroid gland volume and a lower risk of developing goiter or solitary nodules. The body's hormones work together in a finely coordinated and complex system to keep us healthy and functioning. In rats, chronic alcohol exposure induced an increase in TRH mRNA in neurons of the PVN, but the animals no longer responded to peripheral stimulation of thyroid hormone secretion by exposure to cold (Zoeller et al. Anabolic: Pertaining to the metabolic processes by which organisms convert substances into other components the body needs. First, acinar cells secrete digestive enzymes into the small intestine, thereby supporting digestion. However, there are two main exceptions when long-term damage can be severe and life-altering.

The only known endocrine factor released by BAT is the active thyroid hormone T3. Abnormal glucose tolerance and alcohol consumption in three populations at high risk of non-insulin-dependent diabetes mellitus. Alcohol causes inflammation in a part of your brain called the hypothalamus, which disrupts your brain's ability to receive signals related to insulin needs in the body. Life Sciences 31(15):15871596, 1982. For more information, see the sidebar Alcohols Effects on the HypothalamicPituitaryGonadal Axis During Puberty.. Pharmacology, Biochemistry, and Behavior 140:2732, 2016. Another proposed mechanism for the alcohol-induced decrease in LH secretion during puberty is that even though the hypothalamus produced more LHRH, the release of the hormone to the pituitary gland was diminished (Dees and Skelley 1990). ; Ajmo, J.M. CRF release by cells from the PVN of the hypothalamus activates this BEP synthesis and release, which then inhibits further CRF release, creating a negative feedback cycle (Plotsky et al. In these analyses, the HPA response after several weeks of daily 30-minute self-administration of alcohol was highest in the animals with the lowest level of consumption (<0.2 mg/kg/session) and most blunted in animals with the highest level of consumption (~1.0 mg/kg/session). Alcohol also affects reproductive hormones in postmenopausal women. 2000), transforming growth factor alpha (Ojeda et al. Is There a Link Between Diabetes and Depression? ; et al. The more intoxicated you get, the more areas of the brain are compromised by the neurochemical reactions.

Alcohol effects on naloxone-stimulated luteinizing hormone, follicle-stimulating hormone and prolactin plasma levels in female rhesus monkeys. Emanuele, N.V.; LaPaglia, N.; Steiner, J.; et al. These islet cells can be further subdivided into - and -cells. PMID: 25463629, Thayer, J.F. When an individual is past the point of intoxication, their body stops responding to the brains most basic functioning and things as simple as breathing or a controlled heart rate can become impossible. Inhibition by naloxone of the rise in hypothalamic dopamine and serum prolactin induced by ethanol. ; Bryant, C.A. Specifically, alcohol contracts brain tissue and depresses the central nervous system. Ethanol-induced alterations in the morphology and function of the rat ovary. The activity of 5-II deiodinase, however, was only inhibited in the amygdala of the rats that were behaviorally dependent on ethanol but was normal in the non-dependent rats. ; Simonyl, A.; and Rudeen, P.K. How the Body Responds to Alcohol Alcohol acts primarily on the nerve cells within the brain. See full answer below. 2008; Xu et al. If the hypothalamus is injured, it can cause a number of problems in the body, including unexplained weight gain, fatigue, reduced sex drive, and neurological issues like brain fog and memory loss. Neurons are the fundamental reason for our body's responses as they send and receive messages from our brains to other parts of our body on how we should behave or react. PMID: 7215157, Mandrekar, P.; Bala, S.; Catalano, D.; et al. Clinically, the most important of these are alcohol-induced 'pseudo-Cushing's syndrome' and a syndrome of hypothalamic-pituitary-adrenocortical unresponsiveness, both of which result from long-term over-indulgence, and impairment of testosterone secretion which may occur following relatively short-term drinking. For example, alcohol exposure reduces circulating GH and IGF-1 levels. Taxing the liver with alcohol can make . Damage to the hypothalamus can be blamed for the increased need to urinate and lowered heart rate. Oops! Inhibition of nitric oxide synthase prevents the alcohol-induced decrease in testosterone (Adams et al. Frontiers of Hormone Research 38:3241, 2010. Federal government websites often end in .gov or .mil. ; Mallick, A.; and Styche, A. PMID: 22794200, Jenkins, J.S., and Connolly, J. Adrenocortical response to ethanol in man. 11.

Its ideal to catch the disorder before it gets this far, but, sadly, this is not always a reality.. 2011), has a protective and regenerative effect on -cells, and decreases cell apoptosis in cultured islet cells (Dong et al. Thus, fetal ethanol exposure increased methylation of a regulatory element (i.e., the promoter) of the D2R gene, thereby reducing transcription. The nervous system is responsible for rapid transmission of information between different body regions, whereas the endocrine system, which is composed of a complex system of glands that produce and secrete hormones directly into the blood circulation, has longer-lasting actions. ; and Herman, J.P. Neural regulation of the stress response: The many faces of feedback. Alcohol-dependent individuals have been shown to have lower levels of slow-wave sleep power that was associated with lower levels of GH release compared with normal control subjects (Lands 1999). PMID: 15735217, Lin, H.Z. 1993; Stoop 2014). The posterior or neurohypophyseal lobe of the pituitary contains the terminals of certain neurons (i.e., magnocellular vasopressin- and oxytocin-producing neurons) originating in two specific sections (i.e., the paraventricular nuclei [PVN] and supraoptic nuclei) of the hypothalamus. PMID: 9141148, Emanuele, M.A. Iodine is essential to T4 and T3 production, with T4 containing four, and T3 containing three, iodine atoms. PMID: 11159818. PMID: 23025690, Pienaar, W.P. Alcoholism: Clinical and Experimental Research 7(2):131134, 1983. The -cells produce glucagon, which raises blood glucose levels by stimulating the liver to metabolize glycogen into glucose molecules and to release the glucose into the blood. PMID: 19752239, Giustina, A.; Mazziotti, G.; and Canalis, E. Growth hormone, insulin-like growth factors, and the skeleton. Annals of the New York Academy of Sciences 689:146160,1993. ; et al. In the testes, alcohol can adversely affect the Leydig cells, which produce and secrete the hormone testosterone. You may have seen an alcoholic gait before. Continued use of alcohol can cause atrophy of the cerebellum - a shrinkage of the brain. doi:10.1016/j.ecl.2013.05.008, Steiner JL, Crowell KT, Lang CH. For example, acute ethanol administration increased serum prolactin levels in male (Seilicovich et al. Alcohol 12(6):581587, 1995. The researchers suggested that ethanol concentrations in the blood might be an important factor influencing adiponectin secretion and, consequently, insulin sensitivity. At the anterior pituitary, CRF binds to CRF1 receptors and stimulates specific cells (i.e., corticotropic cells) to synthesize and secrete a peptide called proopiomelanocortin (POMC). 2008) as well as reduced responsiveness of the pituitary to CRF (Sarnyai et al. Alcohol exposure during the developmental period induces beta-endorphin neuronal death and causes alteration in the opioid control of stress axis function. Impact of Alcohol on Glycemic Control and Insulin Action. The researchers noted that testosterone, estrogen, and glucocorticoids interact with each. Acute alcohol effects on plasma estradiol levels in women. Toxicology 326:4452, 2014. 1996). Neuropsychopharmacology 29(6): 11561165, 2004. 2002). Dopamine also can block prolactin release directly at the level of lactotropes. During puberty, however, LHRH release is triggered by a variety of stimulatory agents, such as insulin-like growth factor-1 (IGF-1) (Hiney and Dees 1991), norepinephrine (Sarkar et al. After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. Diabetes Care 27(1):184189, 2004. Alcohol ingestion inhibits the increased secretion of puberty-related hormones in the developing female rhesus monkey. This part of the stress response also is regulated by BEP produced from POMC in the hypothalamus, which not only modulates CRH release but also can help decrease the stress response and return the body to a state of homeostasis. IUBMB Life 60(12):790797, 2008. 1991). PMID: 18034699, Seilicovich, A.; Rubio, M.; Duvilanski, B.; et al. Almost every organ and cell in the body is affected by the endocrine system. PMID: 5656299, Jensen, T.K. Neuroendocrine consequences of alcohol abuse in women. In addition, experiments in another cultured -cell line indicated that heavy alcohol consumption may induce -cell dysfunction in type 2 diabetes by increasing the production of reactive oxygen species and inducing apoptosis in the cells (Dembele et al. Stabilization of tumor necrosis factor-alpha mRNA in macrophages in response to chronic ethanol exposure. Psychopharmacology (Berlin) 87(4):461463, 1985. Chronic ethanol consumption increases plasma leptin levels and alters leptin receptors in the hypothalamus and the perigonadal fat of C57BL/6 mice. PMID: 16604091, Bateman, A.; Singh, A.; Kral, T.; and Solomon, S. The immune-hypothalamic-pituitary-adrenal axis. Several studies, including the large NIHAARP Diet and Health Study that followed 490,000 participants (males and females) over 7.5 years, have shown a significant reduction in the risk of developing all types of thyroid cancers in people who consumed two or more alcoholic drinks per day, especially in men. These receptors then translocate to the cell nucleus, where they bind to specific DNA sequences called glucocorticoid response elements of genes that are responsive to glucocorticoids, thereby positively or negatively regulating the expression of those genes. PMID: 12766631, Ehrenreich, H.; tom Dieck, K.; Gefeller, O.; et al. The hypothalamus coordinates the automatic functions in the brain and regulates the release of hormones. There, ACTH stimulates the production of glucocorticoid hormonesmainly cortisol in humans and corticosterone in rodents. Follow up study among couples planning first pregnancy. Total Integrated Response: A measure of the area under the curve of the insulin or glucose response to an oral glucose challenge used to determine insulin resistance. Chronic alcohol ingestion decreases pituitary-thyroid axis measures in Fischer-344 rats. Chronic daily ethanol and withdrawal: 1. In addition, exposure of ovariectomized rats to ethanol for 2 to 4 weeks reduced the expression of two other G-proteins, Gi2 and Gi3 (Chaturvedi and Sarkar 2008). The hypothalamus and pituitary glands in the brain produce hormones that maintain normal testicular function. 2013). Alcohol interferes with communication between nerve cells and all other cells, suppressing the activities of excitatory nerve pathways and increasing the activities of inhibitory nerve pathways. Similarly, healthy men who were in the top percentile of self-reported alcohol consumption had higher levels of excreted cortisol in urine (Thayer et al. Effect of moderate alcohol consumption on adipokines and insulin sensitivity in lean and overweight men: A diet intervention study. Show more Show more How Alcohol. ; et al. Wynne, O., and Sarkar, D.K. Alcoholism: Clinical and Experimental Research 34(11):18351842, 2010. If you want to become sober, finding a support system to help you on the daunting journey is crucial. If the user continues drinking, the hypothalamus and amygdala become affected. Studies have shown that alcohol intake consistently induces an increase in estradiol levels in humans (Mendelson and Mello 1988; Muti et al. But, if no one intervenes, an individual is at risk of it progressing quickly into Korsakoff psychosis, which is incurable. Get help when you need it. ; et al. PMID: 11453951, Kuhn, P., and Sarkar, D.K. It is responsible for making hormones that affect many body functions. Alcoholism: Clinical and Experimental Research 37(3):484489, 2013. A 2014 study looked at how stress and sex hormones affect dopamine neurotransmission during adolescence. 3. 2004). Alcohol can disrupt the production of luteinizing hormones and follicle stimulating hormones, which can lead to harm to the sperm Alcohol can harm the hypothalamus and the anterior pituitary gland Heavy alcohol use can lower testosterone levels Alcohol use can affect sperm count, shape and motility Thus, it is not surprising that cognitive processes are exquisitely sensitive to the effects of chemicals such as alcohol. ; Hendriks, H.F.; et al. 2004; Thamer et al. Acute exposure of healthy men to ethanol (1.5 g/kg) reduced the nightly peak of GH secretion (Valimaki et al. ; Simonyl, A.; and Rudeen, P.K. Alcoholic hypogonadism: Hormonal response to clomiphene. The levels of free T4 and T3, however, were lower in people with AUD during withdrawal and early abstinence compared with nonalcoholic healthy control subjects (Hegedus et al. Similarly, De Marinis and colleagues (1993), using an agent that can stimulate GHRH secretion (i.e., clonidine), demonstrated that the pituitary response to GHRH was intact in abstinent alcoholics. Moreover, chronic alcohol has inhibitory actions on LHRH-producing neurons. PMID: 2106089, Dees, W.L. Growth Hormone & IGF Research 14(Suppl. ; Arner, P.; Caro, J.F; et al. The rise in estradiol through a feedback mechanism is responsible for the surge in LH and FSH levels that occurs in the middle of the menstrual cycle. Blood 96(5):17231732, 2000. The activity of the HPA axis is regulated through several feedback mechanisms. Studies in both humans and animal models have helped shed light on alcohols effects on various components of the endocrine system and their consequences. 2001; Sarkar 2010). The POMC in the anterior pituitary primarily is processed into ACTH, whereas BEP mainly is derived from POMC produced in the hypothalamus (i.e., the ventromedial arcuate nucleus). (Like changing cold butter to a more liquid form like warm margarine.). Mice lacking a functional CRF1 receptor progressively increased their ethanol intake when subjected to repeated stress; this effect seemed to persist throughout their life (Sillaber et al. Alcohol acts as a depressant for the. This can happen after just one or two drinks. 198211. Growth hormone/insulin-like growth factor-1, Growth hormone/insulin-like growth factor-1, Hypothalamicpituitarythyroid axis, Uterus, mammary glands, male reproductive organs, Glucocorticoids (cortisol, corticosterone), Body stress, metabolism, glucose maintenance, Female reproductive glands and tissues, bones, heart, Maintenance of pregnancy and preparation of breast tissue. 2015). If a user continues to drink at this point, it may affect the brain stem, which induces sleep and can cause irregular breathing and even seizures. Endocrine 14(2):213219, 2001b. The medulla is an area of the brain that regulates breathing, consciousness, body temperature, and other automatic functions. The HPP axis includes two neuropeptidesAVP and oxytocinboth of which are produced by cells whose cell bodies are located in the hypothalamus but that extend to the posterior pituitary, where they release their hormones. This effect may result, at least in part, from altered release of prostaglandin E2 (Hiney and Dees 1991), which normally mediates stimulation of LHRH release by norepinephrine. Long-term observation of the hypothalamic-pituitary-thyroid (HPT) axis in alcohol-dependent patients. Some studies have shown that moderate alcohol consumption improves peripheral insulin sensitivity without affecting insulin secretion from pancreatic -cells (Avogaro et al. ; Bergmann, A.; and Thuler, L.C. In men, they are responsible for: In women, hormones perform many functions, including: Chronic drinking can interfere with all of these reproductive functions. There are two types of adipose tissuewhite adipose tissue (WAT) and brown adipose tissue (BAT)that differ in their morphology and function. PMID: 16489593, Verbalis, J.G. This system ensures proper communication between various organs, also interfacing with the immune and nervous systems, and is essential for maintaining a constant internal environment.
