Immune checkpoint inhibitor (ICI)-associated adrenal insufficiency is rare but may become a serious adverse event in patients treated with ICIs. The present case report documents two cases of adrenal insufficiency developed during chemotherapy plus tislelizumab (百泽安, Baize'an; BeiGene Ltd.) therapy in patients with advanced gastric cancer. Adrenal insufficiency developed after 6 and 13 cycles of treatment and was well controlled with hydrocortisone. The patients also developed hypothyroidism, which was managed with levothyroxine. Two patients showed a partial response, and one patient out of two achieved a near-complete response, sustaining over 11 months. Increased awareness of ICI-related adrenal insufficiency is crucial for early detection and prompt management of patients treated with ICIs.

Objective : Hypothyroidism is a syndrome characterized by symptoms such as cold intolerance, or weight gain. Because of side effects of Western medicine treatment, interest in oriental medicine has been increasing. In this study, we examined the therapeutic effects of Evodiae fructus and histological modification in hypothyroidism rat model induced by PTU(6-propyl, 2-thiouracil). Methods : After inducing hypothyroidism in the rats by PTU injections, we divided the rats into four groups, the Evodiae fructus 100 500, control, and $LT_4$ (levothyroxine) groups. After 2 weeks Evodiae fructus and $LT_4$ were administered, respectively. The weight was measured once a week. After sampling the blood for biochemical analysis to check the levels of $T_3$, $T_4$ and TSH, the thyroid tissue was removed, stained with H&E, and an image was obtained using an optical microscope. Results : Compared with normals, controls showed low $T_4$ and high TSH. The Evodiae fructus group showed a statistically meaningful $T_3$ increase to be dose related. But the levels of TSH showed no meaningful difference between the Evodiae fructus group and normals. About the biochemical tests(liver, kidney etc) and weight change, there was no meaningful difference between the Evodiae fructus group and controls. In the biopsy, the Evodiae fructus group showed thyroid tissue improvement compared to controls. Conclusions : These results show that Evodiae fructus stimulates the decreased functions of the thyroid, and also has thyroid cell protecting effects. The lab results also showed that Evodiae fructus is a safe substance that doesn't cause hepatotoxicity or nephrotoxicity. Therefore it is an effective substance in the treatment of hypothyroidism.

In order to study comparatively the effects of "Palmisoyo-San gamibang(八味消遙散加味方)"(AP), "Gyebu-Tang(桂附湯)"(GT) and "Boganyangje(補肝陽劑)" (BG) on the thyrotoxicosis rats, we have made thyrotoxicosis rat model by administration sodium levothyroxine p.o. during 4 days(Control group), and have administered solid extract of AP(236.8mg/200g/day : Sample I group), GT(80mg/200g/day : Sample II group) and BG(70.4mg/200g/day : Sample III group) p.o. to thyrotoxicosis rats during 3 days from 3rd day. We measured the body weight(BW), body temperature(BT), levels of Serum $T_3{\cdot}T_4{\cdot}free\;T_3{\cdot}free\;T_4$ and TSH after administrating solid extract of AP, GT and BG. The results are summarized as follows: 1. Sample I group showed significantly high increasing rate compared with Control, Sample II and Sample III group, but it showed significantly lower levels of BT, $T_4$ and free $T_4$ than those of Control, Sample II and Sample III. group. 2. We could know that AP suppress the alteration of $T_4$ to $T_3$. 3. Sample II and Sample III group showed opposite results to Sample I group in the BW., BT, $T_4$ and free $T_4$ Especially Sample III was significantly higher than Control, Sample I and Sample II, so we could guess that BG stimulates the formation of thyroid hormones. According to the above experimental results, "Palmisoyo-San\;gamibang(八味消遙散加味方)" is assumed to have a curative effect against the thyrotoxicosis rat induced by sodium levothyroxine, and to suppress the alteration of $T_4$ to $T_3$. And we can suppose that "Boganyangje(補肝陽劑)" has a curative effect against the hypothyroidism.

Objectives: This study was to evaluate the effect of Jaeumkanghwa-tang (JEKHT) on the propylthiouracil (PTU)-induced rat hypothyroidism. Methods: Six groups, each of 8 rats per group were used in the present study - intact vehicle control, PTU control, Levothyroxine ($LT_4$), JEKHT 500, 250 and 125 mg/kg treated groups. JEKHT were administered once a day for 42 days as an oral dose of 500, 250 and 125 mg/kg, and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. The changes on the body and organ weight, serum hormone and lipid profiles, liver and testis antioxidant defense factors were observed with histopathology of organs. Results were compared with $LT_4$ 0.5 mg/kg intraperitoneally treated rats in this experiment. Results: PTU treatment, marked decrease of body weight, increases of thyroid weight, decreases of liver, testis, epididymis and prostate weights, decreases of serum Tri-iodothyronine ($T_3$), and Thyroxine ($T_4$) level with increase of serum Thyroid-stimulating hormone (TSH) level, decreases of serum testosterone and dihydrotestosterone (DHT) level with increases of serum Follicular stimulating hormone (FSH) level, increases of serum High density lipoprotein (HDL), decrease of triglyceride content, increase of serum Aspartate aminotransferase (AST) level, decreases of liver and testis antioxidant defense factors were observed. In addition, marked hyperplasia of follicular cells with decreases of follicular colloid contents and diameters was additionally demonstrated with the decrease of hepatocyte numbers per unit area due to hypertrophy of hepatocytes related to lipid droplet depositions, increase of a/oligospermatic epididymal tubules with epididymal atrophic changes, seminiferous tubular atrophy with decrease of stage I~II seminiferous tubules in testis, prostate tubular atrophic changes at histopathological inspections. However, these PTU induced hypothyroidism and related hepatic and male reproductive organ damages were favorably and dose-dependently inhibited by treatment of JEKHT 500, 250 and 125 mg/kg, and JEKHT also effectively regulated the PTU-induced abnormal antioxidant defense factor changes in the both liver and testis. Conclusions: JEKHT 500, 250 and 125 mg/kg dose-dependently inhibited PTU-induced hypothyroidism and related liver and male reproductive organ damages in rats.

Objectives : In present study, we investigated a therapeutic effect of Astragali Radix on hypothyroidism rat model induced by 6-Propyl-2-thiouracil (PTU). Methods : Six-week-old male Sprague-Dawley rats were divided into five groups : Group one included the normal mice. Group two was administrated PTU. Group three and four were administrated the aqueous extract of Astragali Radix 150 and 300 mg/kg before start of PTU treatment. Group five (Positive control) was administrated with levothyroxine 0.5 mg/kg. During this moment the body weight, liver $H_2O_2$ and catalase (CAT) amount, serum thyroid hormone, serum asparte aminotransferase (AST) and alanine aminotransferase (ALT), gland weights were measured with histopathological changes of thyroid glands. These results were compared with levothyroxine 0.5 mg/kg treated rats. Results : The PTU treatment lead to marked decreases of body weight, level of thyroid hormone in serum and liver CAT activation. Also, PTU treatment increased thyroid gland weight, thyroid gland hormone TSH, liver $H_2O_2$ amount and level of AST in serum. On the other hands, the administration of Astragali Radix extract increased body weight gains and ameliorated histopathological changes of thyroid such as hyperplasia of follicular cells with of follicular colloid contents and sizes. In addition, the administration of Astragali Radix extract increased level of $T_4$ in serum, CAT activation in liver. Moreover, the administration of Astragali Radix extract decreased levels of TSH and AST in serum and $H_2O_2$ amount in liver Conclusions : This study suggests that Astragali Radix extract has therapeutic effects on hypothyroidism via promoting thyroid hormone production.

This study was to elucidate the effects of Ukgan-san on the hyperthyroidism induced by sodium levothyroxine. Hyperthyroidisms were induced by continuous subcutaneous treatment of LT4, 0.3 mg/kg, once a day for 27days, and 1,500, 1,000 and 500 mg/kg of Ulkansan extracts were orally administered, once a day for 15 days from 12th LT4 treatment, and the changes on the body, thyroid gland, liver and epididymal fat pad weights, serum triiodothyronine(T3), thyroxine(T4), thyroid-stimulating hormone(TSH), asparte aminotransferase (AST) and alanine aminotransferase (ALT) concentrations, hepatic lipid peroxidation(LPO), glutathione(GSH), superoxide dismutase(SOD) and catalase(CAT) activities were investigated with throid gland, liver and epididymal fat pad histopathological changes. The effects of Ukan-san extracts were compared with that of propyl thiouracil(PTU), a standard antithyroidic drug 10 mg/kg(intraperitoneally). 1,500 and 1,000 mg/kg of Ukan-san extracts reversed all LT4-induced hyperthyroidisms and these effects indicating their potential in the regulation of hyperthyroidism. Further, the Ukan-san extract normalized LT4-induced liver oxidative stresses, and also reduced liver damages and epididymal fat pad reducements suggesting its antioxidative and relative organ protective nature. However, nor favorable effects on LT4-induced hyperthyroidisms were detected in Ulkansan 500 mg/kg treated rats as compared with LT4 control rats in the present study. These effects of Ukan-san may help improvement of hyperthyroidisms and accompanied various organ damages.

Objectives: This study was to evaluate the effect of Palmijihwang-whan (PMJHW) aqueous extract in the regulation of hypothyroidism related reproductive organ damages in propylthiouracil (PTU)-induced rat model. Methods: PMJHW aqueous extract (yield=17.90%) were administered, once a day for 42 days from 2 weeks before start of PTU treatment as oral doses of 500, 250, and 125 mg/kg (body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. Results: PTU-induced hypothyroidism and related male reproductive organ damages-atrophic changes of testis, epididymis and prostate, were favorably and dose-dependently inhibited by treatment of PMJHW 500, 250, and 125 mg/kg. They also effectively regulated the PTU-induced abnormal antioxidant defense system changes in the testis. Although levothyroxine also favorably inhibited PTU-induced hypothyroidism, it deteriorated the hypothyroidism related male reproductive organ damages through testicular oxidative damages. The results suggest that oral administration of 125, 250, and 500 mg/kg of PMJHW has favorable effects on the hypothyroidism and related reproductive organ damages through augmentation of antioxidant defense system in the testis. Conclusions: This study suggest that PMJHW may be help to ameliorate the hypothyroidism and related organ damages in clinics.

The objective of the present study is to determine whether blue honeysuckle lyophilized concentrated powder (BH) has favorable effects on hypothyroidism and related reproductive organ damage. Hypothyroidism was induced by 9 subcutaneous administration of propylthiouracil (PTU) for 28 days. Levothyroxine (LT4)-treated group was intraperitoneally injected with LT4 for the same period, while for BH (125, 250, and 500 mg/kg) or Flos Lonicerae lyophilized aqueous extract (LF, 250 mg/kg)-treated groups, the test materials were orally administrated for 42 days: two weeks before PTU injection and during PTU administration. The changes in serum thyroid hormone levels, serum male sex hormone levels, and testis antioxidant defense system were observed by histopathology of the thyroid gland, epididymis, prostate, and testis. The oral administrations of 125, 250, and 500 mg/kg of BH showed favorable effects compared to LF on hypothyroidism and related damages of reproductive organs through augmentation of the antioxidant defense system in the testis. In conclusion, BH is a promising new potent thyroid gland protecting agent.

A 7-year-old female American cocker spaniel presented with chronic regurgitation and megaesophagus on radiography at a local hospital. Dry and coarse hair coat, tail alopecia, and bradycardia were observed during physical examination. Mild, non-regenerative anemia was indicated by complete blood count (CBC) analysis. Concurrent hypercholesterolemia and hypertriglycemia were indicated by biochemistry tests. Decreased levels of total and free thyroxine (T4) and increased canine thyroid stimulating hormone (cTSH) levels were also detected. Megaesophagus was confirmed by radiographic examination. Based on the results, a diagnosis of hypothyroidism with megaesophagus was made. The patient was initially treated with levothyroxine sodium at a dosage of 0.02 mg/kg twice a day. After two weeks of treatment for hypothyroidism, the dilated esophagus returned to its original size and no further regurgitation was observed. No relapse was observed during two months of follow-up.
