Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lignosus rhinocerus (Tiger Milk mushroom) is distributed in South China, Thailand, Malaysia, Indonesia, Philippines and Papua New Guinea. In Malaysia, it is the most popular medicinal mushroom used by the indigenous communities to relieve fever, cough, asthma, cancer, food poisoning and as a general tonic. In China, this mushroom is an expensive traditional medicine used to treat liver cancer, chronic hepatitis and gastric ulcers. The sclerotium of the mushroom is the part with medicinal value. This rare mushroom has recently been successfully cultivated making it possible to be fully exploited for its medicinal and functional benefits. The present study was carried out to evaluate the chronic toxicity of the sclerotial powder of Lignosus rhinocerus cultivar (termed TM02), its anti-fertility and teratogenic effects as well as genotoxicity. MATERIALS AND METHODS Sprague Dawley rats (10 rats/group/sex) were fed orally with 250, 500 and 1000 mg/kg of sclerotial powder of TM02. The sclerotial powder was orally administered once daily and consecutively for 180 days. At the completion of the oral feeding period, analysis of hematological and clinical biochemical parameters, urine profiles, organ weight as well as histopathological analysis were carried out. The effect of the sclerotial powder on fertility and its possible teratogenicity were examined by feeding rats orally with 100 mg/kg sclerotial powder consecutively for 7-8 weeks. Genotoxicity was evaluated by Ames test using Salmonella typhimurium strains TA 98, TA 100, TA 1535, TA 1537 and Escherichia coli WP2 uvrA. RESULTS The results showed that oral administration of the sclerotial powder of the Lignosus rhinocerus cultivar at daily dose of up to 1000 mg/kg for 180 days had no adverse effect on the general clinical observations, body weight, hematology, clinical biochemistry, urinalysis, absolute organ weight as well as relative organ weight, nor induced histological changes in the organs. Oral administration of 100 mg/kg sclerotial powder of the Lignosus rhinocerus for 7-8 weeks did not affect the fertility of the rats nor induce teratogenic effect on their offspring. Lignosus rhinocerus sclerotial powder up to 5000 μg/plate in the presence and absence of metabolic activation did not cause gene mutations by base pair changes or frameshifts in the genome of the tester strains used. CONCLUSION Our results showed that the no-observed-adverse-effect level (NOAEL) dose of the sclerotial powder of Lignosus rhinocerus in 180-day chronic toxicity study is more than 1000 mg/kg. Oral feeding of the sclerotial powder at 100mg/kg did not induce adverse effect on rats' fertility nor causing teratogenic effect on their offspring. In the reverse mutation Ames test, the sclerotial powder at all tested concentration did not show any genotoxicity.

Abstract
An in vitro detection method of the gastrointestinal absorption of Pilose Antler protein was established for mixed protein activity. Five bands of protein with molecular weight of 17.8-160 kD derived from the Pilose Antler were extracted and sufficiently labeled with FITC (FITC-PE). The stability and variation of FITC-PE in gastrointestinal circumstances were detected by native polyacrylamide gel electrophoresis and confocal laser scanning microscope. Results showed that the main component of FITC-PE kept invariant after being reacted with artificial gastric fluid and artificial intestinal fluid. The fluorescence signal was detected 20 min after administration in the valgus intestinal purse experiment, and three kinds of protein, with molecular weight of 45, 25, and 17.8 kD, were detected in the mixture of absorbent protein. The research laid the foundation for the further in vivo study of Pilose Antler protein. Meanwhile, it would be an in vitro screening method for the absorption, distribution and metabolism of mixed protein from traditional Chinese medicine.

Abstract
Anti-bone resorption activity of pilose antler blood (Cervus nippon Temminck) were evaluated in ovariectomized Wistar rats. The rats were randomly divided into sham operated group (SHAM), ovariectomized group (OVX) and pilose antler blood treated group. The ovariectomized rats were treated with pilose antler blood orally in 4000 microl/kg daily doses for 10 weeks. Compared with SHAM group, serum 17 beta-estradiol level decreased significantly and osteocalcin level increased significantly in OVX group, indicating successful model of osteoporosis. The experiments showed that the bone mineral density of the lumbar spine and left femur in OVX group decreased remarkably compared to SHAM group but normalized by treatment with pilose antler blood. Additionally, serum levels of insulin-like growth factor-land testosterone were lower obviously in OVX group than those in SHAM group but preserved by pilose antler blood treatment. However, no obvious changes in serum levels of calcium, phosphorus, total alkaline phosphatase and osteoprotegerin were observed among three groups. These results suggested that administration of pilose antler blood was effective in alleviating osteoporosis in ovariectomized rats.

Abstract
To elucidate the influence of processing conditions on pilose antlerś therapic effects, the protein composition and activities were compared on three kinds of pilose antler processed by lyophilization, freezing and traditional short-time heating, respectively. The concentration of the water soluble protein in freeze-dried pilose antler was 126.54 mg/g (Folin-Phenol assay), which was 13.1 times higher than that of heating processed antler. These proteins distributed widely in SDS-PAGE electrophoresis and the protein band between 50.0 kDa approximately 60.0 kDa achieved the highest concentration. The water extract of freeze-dried antler promoted the proliferation and IGF-I secretion of rat osteogenic-like cell UMR-106 by 245.25% ( MTT assay) and 66.36 ng/ml, which was respectively 2.2 times and 1.2 times of those of heating processed antler. The same candidate inhibited the growth of human hepatic carcinoma cell BEL-7402 by the highest rate of 47.64% , which was 1.4 times of heating processed antler. The activities of frozen fresh pilose antler were lower than those of its freeze-dried counterpart, but were much higher than those of heating processed antler. The results indicated that lyophilization help to remain the activity of pilose antlerś proteins as much as possible and improve its efficacy.

Abstract
AIM Polypeptide from Chlamys farreri (PCF, molecular mass is 879) is a new marine polypeptide compound isolated from Chlamys farreri. This study investigates the possible protective roles and the mechanism of PCF against ultraviolet B (UVB)-induced apoptosis in murine thymocytes. METHODS The rate of apoptosis and caspase-3 activation was measured by flow cytometry. The expression of stress-response genes c-fos and c-jun was observed by RT-PCR. Western blot analysis was performed to determine the release of cytochrome c. RESULTS It was found that UVB induced murine thymocyte death. The cells treated with UVB showed an increase in cytochrome c release, caspase-3 activity, as well as in the expression of c-fos and c-jun. In addition, all were involved in UVB-induced cell apoptosis. CONCLUSION Our present observations pointed to the ability of PCF to avert UVB-induced apoptosis in thymocytes by modulating c-fos and c-jun expression, cytochrome c release, and the consequent activation of caspase-3, which were essential components of the UV-induced cell apoptotic pathway. The results suggested that PCF is a promising protective substance against UV radiation.

Except the control group, the other groups were sensitized with ovalbumin (OVA) by a combination of intraperitional injection and repeated intranasal challenges to establish the guinea pigs asthma model. However, in the control group, normal saline was used. The morphological changes of bronchial tube, the lung tectology and the inflammation germ cell quantity of eosinophils (Eos), lymphocytes (Ly), neutrophils (Neu) and total blood cells in the blood and bronchoalveolar lavaga fluid (BALF) were examinated in each group respectively. RESULT The levels of Eos, Ly, Neu and total cell quantity in the blood and BALF after the earthworm decoction treatment in the large dosage group were significantly lower than those in the model group (P <0.01), and in the low dosage group were lower too (P <0.05). The Earthworm decoction large dosage could obviously improve the bronchial tube epidermis damage, the mucous membrane gland proliferation and hydrops, asthma pathology change and basilar membrane accumulation. Eos apoptosis was obsered in the bronchoalveolar, blood and BALF. The Earthworm decoction small dosage had a similar effect but slightly to the large dosage. CONCLUSION The Earthworm decoction can lighten the airway inflammation in asthmatic guinea pigs, its mechanism is related with the inhibition of Eos infiltration, acceleration of Eos apoptosis and improvement of the bronchial tube and the lung tectology changes. The effect of the decoction is dose-dependent.

Abstract
OBJECTIVE To study the effects of C. versicolor petroleum ether extracts (CVPE) on the adenohypophysis androgen receptor level in mature castrated male rats. METHOD All the rats in experiment were anesthetized for bilateral testicular and epididymis removal under sterile condition. The rats were randomized into four groups on the 14 th day after operation. The first group was intragastric physiological saline for castratered control group. The second group was intragastric CVPE 2 g x kg(-1) for low-dose group. The third group was high-dose group by giving CVPE 4 g x kg(-1). The fourth group was injected hypodermic testosterone propionate for positive-effect drug treatment group. The drug was given orally to animals one time a day successively for 21 days. The androgen receptor (AR) in adenohypophysis of mature castrated male rats was determined by the immunohistochemistry method and the level of serum testosterone (T) were determined by the radio-immunoassay after ig CVPE for 21 days. RESULT The immunohistochemistry results showed that positive cell numbers of androgen receptor in positive control and each CVPE groups were more than those in the castrated control group. The serum T level was increased greatly in mature castrated male rats treated with CVPE compared with the control group (P < 0.05, P < 0.01). CONCLUSION The results show that CVPE can increase the adenohypophysis androgen receptor and serum T level in mature castrated male rats. It is indicated that CVPE has the effects on the hypophysis function.

Abstract
OBJECTIVE To study anti-atherosclerotic mechanisms of divided functional recipes of Dahuang Zhechong pill (DHZCP) in rabbits. METHOD The atherosclerotic rabbit model was established by high fat feeding combined with immune endothelial injury. Male New Zealand rabbits were divided into 9 groups: normal control group, model control group, Danshen positive control group, and 6 DHZCP-divided groups including divided functional recipes No. 1, 2, 3 with low and high doses for each divided recipe. After intragastric administration for 60 days, blood lipids and serum MDA and NO levels and SOD activity and plasma ET concentration, and contents of hydroxyproline and proteins in the vascular wall were determined. RESULT Compared with the model group, the level of blood lipids did not significantly change, serum MDA and ET levels, and the contents of hydroxyproline and proteins in the vascular wall significantly decreased (P < 0.05), and SOD activity and NO level increased in the divided functional recipes (all P < 0.05). CONCLUSION The divided functional recipes of DHZCP can inhibit development of atherosclerosis via a non-lowering lipid mechanisms, including anti-peroxidation of lipids, protection of endothelial function, and decrease of formation of extracellular matrix by reducing synthesis of collage and protein on the vascular wall. Among them, the divided functional recipe No. 1 exhibits the most obvious effect.
