Objectives The purpose of this study is to find out how taking oriental herbal medicine may affect the sex hormone levels in a patient who was diagnosed with prematurity. Methods We prescribed 120 cc of oriental herbal medicine twice daily for a month to a patient suspected of the precocious puberty due to 11 pg/ml of the estradiol level. Upon finishing the course of oriental herbal medicine, the patient was retested for the follicular stimulating hormone, luteinizng hormone and estradiol levels. Results After administration, all levels of luteininzing hormone, follicular stimulating hormone and estradiol were decreased. There was no diagnosable evidence for the idiopathic central precocious puberty in the gonadotropin releasing hormone stimulation. Conclusions Oriental herbal medicine is a good alternative treatment of choice for the precocious puberty. However, more in-depth studies are to be followed.

The purpose of this report is to evaluate effect of Korean medical treatment on idiopathic gonadotropin-dependent precocious puberty (G-DPP) patient received herbal medicine. We administered Aesopjiyoun-tang remedy to idiopathic G-DPP and analyzed the delay effect by hormonal value and radiographs; the height growth effect by measurement of height. After Korean medical treatment, suppression effect to peak-Luteinizing Hormone level (LHL) is 14.39IU/L to 10.9IU/L for 13month, growth effect to height value is 11cm/13month; and change of mean growth velocity (MGV) is 6.08cm/year to 10.06cm/year. The gain in height by treatment is 3.98cm/year. The result suggests Aesopjiyoun-tang can be an effective treatment for G-DPP. Herbal medicine can be used as an alternative treatment in place of the GnRH treatment.

This study was conducted to examine DA-3002, a biosynthetic human growth hormone, for its acute and subacute toxicities in mice and rats. The drug was administered subcutaneously and orally at a dose level of 1.0, 3.0, 8.9, 26.7 or 80.0 lU/kg once for single dose toxicity and given subcutaneously at a dose level of 0.34, 1.7 or 8.4 lU/kg daily for 13 weeks to investigate repeated dose toxicity. In the acute toxicity study, doses up to 80 lU/kg had no adverse effect on the behavior or body weight gain. Pathological examinations revealed no abnormal changes which could be attributed to toxic effect of DA-3002. In the subacute toxicity study, the growth hormone was tolerated well in broth mice and rats. No drug related deaths occurred and all animals appeared to be normal throughout the dosing period. Increases in body weight gain, food utilisation and absolute organ weights were observed in the rats in the high dose group. Mild changes in the blood chemical parameters were also seen in the treated groups. Histopathologically, however, no abnormal changes were observed in any organ. The changes noted during the treatment periods presumably represent exaggerated pharmacological effects of the growth hormone, and no observed adverse effect level (NOAEL) was considered to be more than 8.4 lu/kg/day.

Estrogen is crucial in regulating food intake, energy expenditure, glucose metabolism, and lipid metabolism. During menopause, the decline in estrogen levels predisposes women to weight gain, abdominal obesity, insulin resistance, type 2 diabetes, hypertension, and cardiovascular disease (CVD). Menopausal hormone therapy (MHT) prevents weight gain, improves lipid metabolism by lowering low-density lipoprotein cholesterol while raising high-density lipoprotein cholesterol, and delays the onset of type 2 diabetes in menopausal women. The effect of MHT on CVD in menopausal women remains controversial. The Women's Health Initiative study was terminated prematurely after it revealed that hormone administration increased the risk of myocardial infarction, stroke, and thromboembolism. However, some studies have found that MHT had no effect or decreased the risk of CVD. The inconsistent results were likely due to multiple factors, including the timing of hormone therapy initiation, duration of therapy, type and dosage, and presence or absence of CVD risk factors at the start of treatment. Despite its benefits in terms of managing weight gain and reducing the risk of type 2 diabetes, dyslipidemia, and CVD associated with obesity, it is not recommended as the primary therapy for weight loss or diabetes prevention. MHT is primarily indicated for postmenopausal women, who are likely to benefit from its potential to prevent weight gain and improve lipid metabolism.

Object : This study was to evaluate the effect of Ginseng Radix, aqueous extracts of the root part of Panax ginseng on the 6-n-propyl-2-thiouracil(PTU)-induced rat hypothyroidism. Methods : Aqueous extracts of Ginseng Radix(GR; yield = 11.70%) were administered, once day for 42 days from 2 weeks before start of PTU treatment as an oral dose of 300 and 150 mg/kg(body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10mg/kg for 28 days. The changes in the body weight, thyroid gland weights, serum levels of thyroid hormone-thyroid stimulating hormone(TSH), tri-iodothyronine(T3) and thyroxine(T4), total cholesterol, low density lipoprotein(LDL), high density lipoprotein(HDL) and triglyceride, liver antioxidant defense system-lipid peroxidation, $H_2O_2$, superoxide dismutase(SOD) and catalase(CAT) were observed with histopathology of thyroid glands. Results : Results were compared with LevoT4 0.5mg/kg treated rats. GR extracts suppressed the decreases in the body weight, thyroid gland weights, T3 and T4, TG, liver $H_2O_2$ and SOD activities as results of PTU treatment. And GR extracts suppressed the increases of HDL contents, liver CAT activities, thyroid gland weight as results of PTU treatment. In addition, marked hyperplasia of follicular cells with decreases of follicular colloid contentsand sizes were demonstrated at histopathological inspections. However, these PTU-induced histopathological changes related to hypothyroidism were dramatically decreased by treatment of both different dosages of GR extract, respectively Conclusions : This study suggest that GR extracts have favorable effects on the thyroid hormone productions with beneficial effects on the hypothyroidism mediated by the modulatory effects on the antioxidant defense system.

Plasma steroid hormone levels in the viviparous rockfish (Sebastes schlegeli) were examined in relation to gonadal histology under controlled photoperiods and water temperatures. To investigate those effects in S. schlegeli the photoperiod was maintained at 15L:9D in June and then it was gradually decreased to 9L: 15D in October. It was then gradually increased to 12L:12D in January, followed by 14L:I0D in February. The water temperature was $19-20^{\circ}C$ in July. From August to October, it was from $18^{\circ}C\;to\;12^{\circ}C$. Then, it was dropped to a low of $19-11^{\circ}C$ in November to December and then gradually increased to $14-15^{\circ}C$ in February. In females, both plasma $estradiol-l7\beta\;$ (E2) and testosterone (T) levels from August to February showed a similar pattern in both the treatment and the control groups. In the treatment group, the peaks of plasma E2 and T were observed in November, and the peaks were closely correlated to histological observations. Oocytes contained many yolk globules (final vitellogenic oocytes), and oocytes at the migratory nucleus stage increased in size. Plasma levels of progesterone did not change much throughout the experimental period. However, in the control group, the peaks of E2, T, and progesterone were observed in February. These results indicate that the controlled photoperiod and water temperature accelerated sexual maturity, corresponding to the advancement of plasma E2 and T peaks by approximately 3 months. In males, plasma T levels showed a similar pattern from August to October in the treatment and control groups, though levels in the treatment group were higher than those in the control group. From histological observations, the treatment group copulated one month earlier.

The purpose of this study was to evaluate effects of hormonal treatments on corpus lutea, follicles and development stage of embryos for enhancing the production efficiency of in vivo porcine embryos suitable to introduce fo foreign genes. Hundred and twenty gilts were allocated to 6 experimental group in different combinations of hormones PG 600, PMSG, hCG and altrenogest. When gilts were treated with chorionic gonadotrophin 200 IU and serum gonadotrophin 200 IU(PG 600), altrenogest, serum gonadotrophin (PMSG) 1,000 IU, and chorionic gonadotrophin(hCG) 750 IU (PAPh), the numbers of corpus luteum (30.4) were significantly higher than those of other treatment groups (P<0.05). The number of corpus luteum from ovary in either right (9.1) or left (10.1) side was not significantly changed with hormone treatments. Number of follicles in control was 20.7, which was higher than those of hormonal treatment groups. The average numbers of 1, 2, 4 and 8 cell staged embryos were 8.1, 1.4, 1.6 and 1.0 in control, but the numbers of 1-cell stage in PAPh treatment group was 24.2, which was significantly higher than those of treatment groups (P<0.05). Therefore, these data indicated that hormonal treatment, especially PAPh, enhanced the developments of follicles, corpus lutea and embryos and increased the collection rate of the 1-cell stage embryos to introduce of foreign genes.

Purpose: Recombinant human growth hormone (rhGH) has been widely used to treat short stature. However, there are some concerns that growth hormone treatment may induce skeletal maturation and early onset of puberty. In this study, we investigated whether rhGH can directly affect the neuronal activities of of gonadotropin-releasing hormone (GnRH). Methods: We performed brain slice gramicidin-perforated current clamp recording to examine the direct membrane effects of rhGH on GnRH neurons, and a whole-cell voltage-clamp recording to examine the effects of rhGH on spontaneous postsynaptic events and holding currents in immature (postnatal days 13-21) and adult (postnatal days 42-73) mice. Results: In immature mice, all 5 GnRH neurons recorded in gramicidin-perforated current clamp mode showed no membrane potential changes on application of rhGH (0.4, $1{\mu}g/mL$). In adult GnRH neurons, 7 (78%) of 9 neurons tested showed no response to rhGH ($0.2-1{\mu}g/mL$) and 2 neurons showed slight depolarization. In 9 (90%) of 10 immature neurons tested, rhGH did not induce any membrane holding current changes or spontaneous postsynaptic currents (sPSCs). There was no change in sPSCs and holding current in 4 of 5 adult GnRH neurons. Conclusion: These findings demonstrate that rhGH does not directly affect the GnRH neuronal activities in our experimental model.

This study validated the effect of Vaseline and the vegetable hormone-added medicine that can influence the formation of new calluses on the injured part, with the subjects of natural monument trees and large old trees. The medicines can help in the treatment of the pored or injured parts and promote the formation of new callus on natural monument trees and large old trees, which can help vigorous growth activities and prevent any secondary infection by pathogens at the same time. It turned out that the Vaseline that is used for the protection of cambiums after surgical operations on the trees did not have any significant effect on the formation of calluses. However, since it was found that new calluses formed rapidly when applying the medicine using a vegetable hormone, the medicine is highly recommended for use. If further studies should determine proper medicines for the trees according to the kinds of trees and if the medicine is applied in proper concentrations to the injured part for rapid formation of calluses on the trees when the trees undergo surgical operations, it then should be helpful in preventing the sound part(s) of the trees from decay caused by secondary infection and treatment of the injured part.
