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 bursa of Fabricius from thyroxine-treated group showed increased number of large lymphocytes with well-developed cytoplasm, immunoblasts and proplasmacytes accompanied with active cell divisions. More prominent development of Golgi apparatus and mitochondria in the cytoplasm of the cells in the bursa from this group were also observed. The bursa of Fabricius from the propylthiouracil-treated group, however, distinctively revealed proliferation of fibroblasts in the interstitial tissues, decreased number of lymphocytes, and necrotic lymphocytes in the follicles.

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 : 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.

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.

Propylthiouracil(PTU)을 4주 및 12주간 투여한 흰쥐의 대동맥을 적출하여 혈관수축제와 이완제에 대한 반응을 관찰하여 다음과 같은 결과를 얻었다. PTU를 처치한 실험군에서는 대조군에 비해 현저한 체중저하와 혈중 갑상선호르몬의 감소를 보였다. PTU를 처치한 흰쥐의 대동맥에 대한 norepinephrine (NE)과, calcium및 potassium 이온에 의한 최대수축 반응은 대조군에 비하여 유의하게 감소되었다. 그러나 NE에 대한 중간유효량은 증가되었으나, calcium이온에 대한 중간 유효량은 유의한 차이가 없었다. 그리고 acetylcholine, histamine, isoproterenol 및 nitroprusside에 의한 대동맥의 이완작용은 대조군에 비해 증가된 경향을 보였다. PTU를 12주간 처치한 군에 있어서 acetylcholine에 의한 최대 이완반응은 대조군에 비해 유의하게 증가되었지만 다른 이완제에 의해서는 유의한 차이가 없었다. PTU를 4주간 처치한 군에 있어서는 대조군에 비하여 혈관이완제에 대한 중간억제량은 유의한 차이가 없었지만, 12주 처치군에 있어서는 isoproterenol 및 nitroprusside에 대한 중간억제량은 감소 되었으나 acetylcholine 및 histamine에 대한 중간억제량은 유의한 차이가 없었다. 이상의 결과로 미루어 보아 PTU-처치에 의한 혈관 반응성의 변화는 혈관 내피세포보다는 혈관 평활근세포자체의 변화에 기인되며, 이러한 세포내의 변화는 갑상선 기능이 저하된 후에도 계속되고 있음을 알 수 있었다.

Thyroid hormone의 생합성반응기작을 알아보기 위하여 방사선 I-131을 쥐에 주사한 후 thyroid gland을 분리하여 분석하였다. Pancreatin viokase를 처리하여 분리한 요드화합물을 여지 크로마토그라피로 분리 동정하고 이를 radioautography로 분석한 결과 I-131은 주사후 바로 쥐의 체내에서 흡수되어 monoiodotyrosine이 되고 이것은 diiodotyrosine으로 전환됨을 관찰하였다. 실험결과는 diiodotyrosine은 thyroxine 생합성에 있어서 중간생성물이나 반면 triiodothyronine은 오히려 분해산물임을 보여 주었다. 또한 환원제인 propylthiouracil을 투여한 쥐에서 iodine의 체내집적현상(Iodine Pump)은 현저히 증가하였으나 유기 요도화합물을 전환되는 것을 저하였다.

Objectives : The object of this study was to evaluate the effect of Insamyangyoung-tang aqueous extracts (ISYYT) on the propylthiouracil (PTU) induced rat hypothyroidism. Methods : The rats were divided into 6 groups : intact control, PTU control, Levothyroxine (LT ₄ ), 500, 250 and 125 mg/kg ISYYT treated groups. In ISYYT treated groups, PTU and ISYYT were administered for 4 weeks after 500, 250 and 125 mg/kg ISYYT were administered for 2 weeks. In LT ₄ group, PTU and LT ₄ were administered for 4 weeks. The changes were observed : the weigh, serum thyroid hormone levels, serum sex hormone levels, serum lipid profiles, serum liver enzyme levels, liver and testis antioxidant defense system, histopathology of thyroid gland, liver, epididymis, prostate and testis. Results were compared with PTU control group in this experiment. Results : In comparison with PTU control group, 500 and 250 mg/kg ISYYT treated groups showed significant increase of body, thyroid, liver, testis, epididymis and prostate weights, decrease of serum TSH levels with increase of serum T3 and T4 level, increase of serum testosterone and DHT levels with decrease of serum FSH levels, decrease of serum HDL with increase of TG and increase of serum AST levels. Histopathological inspections of hepatic and male reproductive organ damage induced by PTU were improved. And the changes of antioxidant defense system of Liver and testis induced by PTU were improve. There was no significant difference between 125 mg/kg ISYYT treated group and PTU control group in this experiment. Conclusions : The results obtained in this study considered that Insamyangyoung-tang may be effective in hypothyroidism and related organ damages.
