This study was made to investigate whether there would be any direct relationship between testis and adrenal gland. After the iadministration of testosterone propionate to the hypophysectomized male rats, weight of adrenal glands, each zona rates in adrenal gland and histological changes measured from the 1st day to 56th day of the experimental period. The results obtained were as follows; 1. For the weight changes of thyriod gland, it showed a similar changes between the hypophysectomized and the testosterone propionate treated-hypophysectomized group. However, the weight of adrenal glands for the treatment groups were decreased as the time passed as compared to the control group, and the difference were highly significance at the 7th day and there on. 2. For the zona rates in adrenal gland the changes were similar between the hypophysectomized and the testosterone propionate treated-hypophysectomized group. Zona fasciculata and reticularis were decreased rapidly as time passed as compared to the control group, and the difference were significant at the 7th day and highly significant at the 14th day and there on. Adrenal medulla tended to increase, showing a significance with P<0.05 at 7th day, and P<0.01 at 14th day and there on. Zona glomerulosa showed no differences among the groups. 3. Histological changes for the testosterone propionate treated-hypophysectomized group were similar to the hypophysectomized group. Of adrenal gland, zona fasciculata and reticular is were degenerated and lost their function as time passed after treatment, and zona glomerulosa and adrenal medulla were observed not bo changed. 4. Since there were re no differences in weight changes of adrenal glands, the zonarates in adrenal gland and histological changes between the hypophysectomized and testosterone propionate treated-hypophysectomized group, it would appear that there were no direct relationship between the testis and the adrenal gland, but the involvement of hypophysis might be necessary for the control mechanism.

This study was done to investigate whether cholic acid derivatives have anti-stress activity and what is a cause of this anti-stress effect. Seven cholic acid derivatives (cholic acid, taurocholic acid, ursodeoxycholic acid, tauroursodeoxychoic acid, chenodeoxy cholic acid, dehydrocholic acid, hyodeoxycholic acid) were used, silymarin and valproic acid were used as positive controls. Stress was induced by restraint immobilization technique plus water immersion (24hrs) and adrenal weight, spleen weight, adrenal ascorbic acid, serum cholesterol, lactate dehydrogenase (LDH), alkaline phosphatase (ALP), adrenal cholesterol, glucose and corticosterone levels were measured as stress indicators. Most cholic acid derivatives markedly decreased the adrenal weight, and TUDCA and DHCA increased the spleen weight. The restraint stress induced increments in serum LDH, ALP and cholesterol were attenuated by most cholic acid derivatives. Cholic acid, taurocholic acid and tauroursodeoxycholic acid only increased the content of adrenal ascorbate. While valproic acid showed an inhibitory effect against stress, silymarin did not. Our findings suggest that most cholic acid derivatives have anti-stress effect and that their anti-stress effect is, in part, related to choleretic activity.

Adrenal insufficiency is caused by adrenal failure or impairment of the hypothalamic-pituitary-adrenal axis. The main symptoms of adrenal insufficiency are chronic fatigue, nausea, vomiting, anorexia, and weight loss. We report a case of adrenal insufficiency in a 38-year-old female. The patient complained of headache, dizziness, anorexia, and general weakness. We treated her with Iggisaengjin-tang and acupuncture. After treatment, the patient's symptoms were improved and serum cortisol levels rose to a normal range without the aid of steroid supplementation therapy. This case suggests that Korean medicine can be effective in the treatment of adrenal insufficiency, but more clinical reports are needed.

The purpose of this study was to determine the effect of regular exercise during dexamethasone injection on the body weight, weight of hindlimb muscles and adrenal gland in Young rats. 80-100g Wistar rats were divided into control, exercise, dexamethasone injection(dexa), and exercise during dexamethasone injection(D+E) group. The dexa group received daily subcutaneous injection of dexamethasone at a dose of 5mg/kg body weight for 10 days. The exercise group ran on a treadmill for 60min /day(20 minutes every 4 hour) at l0m/min and a 10$^{\circ}$ grade. The control group received daily subcutaneous injection of normal saline at a dose of 5mg /kg body weight for 10 days. The D+E group ran on a treadmill for 60min /day (20 minutes every 4 hour) at 10m/min and a 10$^{\circ}$ grade. Body weight of both control and exercise group increased significantly until 10 days, that of both dexa and D+E group decreased significantly, resulting in 79.47 and 78.75% decrease respectively compared to the first day of experiment. Body weight and muscle weight of the soleus, plantaris and gastrocnemius decreased significantly with dexamethasone injection. Relative weight of the plantaris and gastrocnemius of the dexa group decreased significantly compared to that of the control group. Body weight and muscle weight of the gastrocnemius of the exercise group increased significantly, and the muscle weight of the soleus and plantaris tended to increase. The Relative weight of the plantaris was comparable to the control group and that of the soleus and gastrocnemius tended to increase in the exercise group. Body weight and muscle weight of the soleus and plantaris of the D+E group showed a tendency to increase, and muscle weight of the gastrocnemius increased significantly compared to the dexa group. The Relative weight of the soleus and gastrocnemius tended to increase, and that of the plantaris of the D+E group increased significantly compared to the dexa group. Body weight, muscle weight and relative weight of the soleus, plantaris and gastrocnemius of the D+E group did not recover to that of the control group. Adrenal gland weight of the dexa and D+E group tended to increase, and that of the exercise group increased significantly. From these results, it can be suggested that regular exercise during dexamethasone injection might attenuate the decrease of body weight and hindlimb muscle weight induced by the dexamethasone injection.

Previous studies, including our own, indicate that distinct morphological changes in rodent adrenal cortex could be induced by exposure of endocrine disrupting chemicals (EDC). In the present study, we conducted histological analyses of adrenocortical substructure using a nonylphenol-treated F1 rat model. The adrenal weight of NP-5000 group was significantly declined in female rats (p<0.001), while the adrenal weights of NP-treated groups were not significantly changed in male rats. The thickness of zona glomerulosa layers of female rats in NP-5000 group was significantly declined (p<0.001) but zona fasciculata layers were not changed. The zona reticularis layers of NP-treated group were significantly thinner than those of control group (NP-50, p<0.05; NP-5000, p<0.01). In male adrenal glands, there was no significant change of zona glomerulosa layers in NP-treated groups while the thickness of zona fasciculata in NP-5000 group was significantly decreased (p<0.01). Like female rats, the thickness of zona reticularis in NP-treated groups was significantly decreased (NP-50, p<0.001; NP-5000, p<0.05). Present study demonstrated that the adrenal histology could be altered by low-dose NP exposure in F1 rats, and the effect might be sexually dimorphic. Further study will be helpful for understanding possible adrenal pathophysiology induced by EDC exposure, and EDC-related sexually dimorphic phenomena in rodent adrenals.

The effect of alteration of light-darkness cycle on the protein metabolism was studied in the rat. The light-darkness cycle was altered either every 3 or 9 days, and animals consumed diets containing 8 or 25% casein. The results were summarized as follows : 1) Food consumptions and body weight gains of the 25% casein groups were higher than those of the 8% casein groups, and, among the animals consumed 25% casein diet, the light-darkness cycle altered group had lower food consumption and body weight gain than the unaltered group. 2) Weights of liver and adrenal gland per l00g body weight were not different with the dietary protein levels, but, at the end of experimental period, the 8% casein diet group of which light-darkness cycle altered every 9 days had the smallest liver weight and the largest adrenal gland weight. 3) Liver nitrogen and plasma protein concentrations of the 25% casein groups were slightly higher than those of the 8% casein groups. 4) Percentages of nitrogen retention of the 25% casein groups at period III were slightly lower in the light-darknerr cycle altered animals than that of the unaltered group.

Effects of mahwang(Ephedrae herba) aqua-acupuncture at sinsoo (B-23)and Jisil(B-52)on adrenal cortical insufficiency were investigated in dexamethasone treated rats. Concentration of serum cortisol was decreased in dexamethasone treated rats. However, these values showed a tendency to increase in mahwang(Ephedrae herba) aqua-acupuncture groups. Concentration of serum total protein was increased in dexamethasone treated rats. However, these values were decreased by the mahwang(Ephedrae herba) aqua-acupuncture. The portion of neutrophils was decreased and the portion of lymphocytes and eosinophils were increased in dexamethasone treated rats. However, in mahwang(Ephedrae herba) aqua-acupuncture groups, the portion of neutrophils showed a tendency to increase and the portion of lymphocytes and eosinophils showed a tendency to decrease. In dexamethasone treated rats, the weight of adrenal glands were decreased, however these values were increased in mahwang(Ephedrae herba) aqua-acupuncture groups.

The objective of this study was to investigate the relationship between changes in body temperature, adiposity and sympathoadrenal activity in normal weight female college students, eating an instant-noodle lunch in a laboratory setting at ambient temperatures of 22-24.8$^{\circ}C$. Preprandial epinephrine(EPI) concentration, as an indicator of adrenal activity, was inversely and significantly correlated with body weight, body mass index(BMI), and waist girth. Changes in pre- and postprandial EPI concentrations showed positive correlations with % body fat, fat mass, waist girth, hip girth, and waist/hip girth ratio(WHR). The preprandial norepinephrine (NE) concentration was negatively correlated with recovery time from the peak postprandial core temperature to the meal-start core temperature(RTST). However, the NE concentration, an indicator of sympathetic neural activity, was not related to anthropometric measurements in normal weight young women. In conclusion, adrenal activity was negatively associated with adiposity and central body fat distribution. Sympathetic activity was related to body temperature regulation capacity after a meal, but was not related to adiposity in normal weight young women. (Korean J Nutrition 31(7) 1130-1138, 1998)

Sorafenib (Nexavar) has been regarded as a treatment for unresectable hepatocellular carcinoma (HCC), with side effects that include hand-foot skin reaction, diarrhea, rash, fatigue, hypertension, nausea, anorexia, weight loss, and alopecia. Thyroid disorder, such as endocrine side effect, has also been reported. However no case involving adrenal insufficiency has been reported. Here, we report a case of adrenal insufficiency which occurred after taking sorafenib in a patient with HCC. A 56-year-old man visited our hospital due to right upper quadrant abdominal pain and he was diagnosed as multiple disseminated and unresectable HCCs with portal vein invasion; therefore transarterial chemoembolization was performed and sorafenib administration was started. Two months later, he was admitted to the hospital complaining of severe fatigue. The laboratory results showed cortisol of <$0.2{\mu}g/dL$ and adrenocorticotropic hormone of <1.00 pg/mL. The patient had no history of taking steroids or herbal medications. Secondary adrenal insufficiency was diagnosed and prednisolone 10 mg per day was started immediately; as a result, fatigue remarkably improved. This may be the first report indicating a possible association between sorafenib and adrenal insufficiency and it implies that the possibility of adrenal insufficiency should be considered in patients taking sorafenib who complain of severe fatigue.
