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 vascular responses to the vasoactive drugs were evaluated using aortic ring preparations obtained from propylthiouracil (PTU)-treated rats. The body weights and the levels of serum thyroxine $(T{_4})$ and triiodothyronine $(T{_3})$ were significantly decreased in propylthiouracil-treated rats as compared with those in age-matched control rats. The contractile responses to norepinephrine and potassium and calcium ions were significantly attenuated in aortic rings of PTU-treated rats 4 weeks after when compared with those from age-matched control animals. By the PTU treatment, however, the sensitivity to norepinephrine but not to calcium was decreased while the maximal responses to norepinephrine and calcium were reduced together. The attenuated contractile responses to the vasoconstrictors in PTU-treated rats are ascribed to the decreased ability of the muscle cells to contract. On the other hand, the relaxation responses induced by acetylcholine and histamine (endothelium-dependent relaxants) and isoproterenol and sodium nitroprusside (endothelium-independent relaxants) had tendencies to be augmented in aortic rings of PTU-treated rats when compared with those of age-matched control animals. However, the sensitivities to the endothelium-independent relaxants were different between PTU-treated and control rats whereas those to the endothelium-dependent relaxants were not. These results suggest that the altered vascular responsiveness in the PTU-treated rats seems to be due to the alteration of smooth muslce cells rather than the Influence of endothelium, and that this change is slowly progressive after hypothyroidism is evident.

Objectives : Hyangsayangyi-tang (香砂養胃湯) is a polyherbal formula, has been used as one of the representative So-eumin (少陰人) prescriptions in Sasang-medicine (四象醫學), a famous Korean medicinal theory. The aqueous extract of Hyangsayangyi-tang (HSYYT) was evaluated for its possible ameliorative effect in the regulation of hypothyroidism related reproductive organ damages in propylthiouracil (PTU)-induced rat model. Methods : HSYYT aqueous extracts were administered, once day for 42 days from 2 weeks before start of PTU treatment as an oral dose of 500, 250 and 125 mg/kg (bodyweight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28days. Results : PTU induced hypothyroidism and related male reproductive organ (testis, epididymis and prostate) damages were favorably and dose-dependently inhibited by treatment of HSYYT 500 and 250 mg/kg, and they also effectively regulated the PTU-induced abnormal antioxidant defense system changes in the testis. No effective or any harmful changes on the PTU induced hypothyroidism and related male reproductive organ damages were observed in HSYYT 125 mg/kg treated rats as compared with PTU control in this experiment. Conclusions : The results obtained in this study suggest that oral administration of 500 and 250 mg/kg of HSYYT showed favorable effects on the hypothyroidism and related reproductive organ damages through augmentation of antioxidant defense system in the testis, and it is considered that HSYYT may be help to ameliorate the hypothyroidism and related organ damages in clinics.

Propylthiouracil (PTU) is one of the most common drugs used in the treatment of Graves' disease. There are a number of side effects found with PTU use including fever, rash, arthralgia, and flu-like symptoms. Recently antineutrophil cytoplasmic antibodies (ANCA) positive vasculitis after PTU treatment was reported as a rare side effect, which can cause diffuse alveolar hemorrhage and glomerulonephritis. A 45-year-old woman with Graves' disease had been treated with PTU for five months, complained of hemoptysis due to pulmonary alveolar hemorrhage causing anemia, and also had hematuria. Simple chest X-ray and HRCT showed bilateral consolidation and bronchoalveolar lavage fluid revealed alveolar hemorrhage. A serologic test was positive for ANCA against myeloperoxidase and proteinase-3. Such findings suggested that the presence of PTU induced ANCA positive vasculitis. Cessation of PTU and the administration of high dose steroids improved the clinical manifestation, radiologic and serologic findings. We observed ANCA titer serially for 6 years. During the follow up period, ANCA titer decreased slowly and stayed within the acceptable upper normal limit.

Objectives The object of this study was to evaluate the effect of Yikgeebohyul-tang aqueous extracts (YKBHT) on the propylthiouracil (PTU)-induced rat hypothyroidism. Methods The rats were divided into 6 groups : intact vehicle control, PTU control, LT4, YKBHT 500, 250 and 125 mg/kg treated groups. Hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. YKBHT aqueous extracts were administered once a day as an oral dose of 500, 250 and 125 mg/kg for 42 days. The changes were observed : weight of body, thyroid gland, liver, testis, epididymis and prostate, serum thyroid hormone levels, serum male sex hormone levels, serum lipid profiles, liver and testis antioxidant system. These results were compared with LT4 0.5 mg/kg intraperitoneally treated rats. Results These PTU induced hypothyroidism and related hepatic and male reproductive organ damages were favorably and dose-dependently inhibited by treatment of YKBHT 500, 250 and 125 mg/kg, and YKBHT also effectively regulated the PTU-induced abnormal antioxidant defense factor changes in the both liver and testis. Although, LT4 also inhibited PTU-induced hypothyroidism and relative liver damages. But it deteriorated the hypothyroidism related testis, epididymis and prostate damages through testicular oxidative damages. Conclusions : The result of this study suggests that YKBHT has favorable effects on the hypothyroidism and related liver and reproductive organ damages with augmentation of antioxidant defense factor in the testis and liver. YKBHT 500, 250 and 125 mg/kg dose-dependently inhibited PTU-induced hypothyroidism and related liver and male reproductive organ damages in rats.

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.

Propylthiouracil(PUT) is a drug which used at Grave's disease. But PTU has recently been observed to associated with antineutrophil cytoplasmic antibody(ANCA)-positive vasculitis resulting in, infrequently, diffuse alveolar hemorrhage. We report the case of a patient who developed diffuse pulmonary hemorrhage after she had been taking PTU for two years. She had received a diagnosis of Grave's disease at two years ago. The serologic study was positive for ANCA with myeloperoxidase(MPO) specificity. Bronchoalveloar lavage(BAL) fluid analysis revealed hemosiderinladen macrophages. Such findings suggested propylthiouracil-induced dffuse pulmonary hemorrhage associated with antineutrophil cytoplasmic antibody. To our knowledge, this represents the first documentation in a case of PTU-induced diffuse pulmonary hemorrhage in Korea.

To determine the interrelationship between thyroid status and the reparitioning action of clenbuterol (CLE) in broilers, two-week-old female chickens were fed diets containing an antithyroid substance, propylthiouracil (PTU, 0 or 0.3%), CLE (0 to 1 mg/kg), or both for 18 days in a $2{\times}2$ factorial design experiment. Muscle weights (breast muscle, gastrocnemius and peroneus longus) increased only in the normal chickens fed CLE. As absolute mass, protein of leg muscle quantitatively increased in the CLE-fed normal birds. In contrast, inhibition of the CLE-induced protein accretion, especially of peroneus longus, occurred in the PTU group. A quantitative increase in DNA was observed in leg muscles of the normal chickens, but no DNA response to CLE was shown in the PTU-treated chickens. The decreased RNA in leg muscles of the PTU group was more reduced by CLE feeding. Although not statistically significant, the reduced degradation rate of whole muscle protein in normal chickens fed CLE was not confirmed in the PTU-fed group. The present study, therefore, concluded that metabolic action of thyroid hormones was a prerequisite for the hypertrophic effect of ${\beta}$-agonist in broilers.

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.
