Through two years of experimental trials,a species of fresh snail rich in protein containing 0. 45mg/kg selenium was obtained

Physico-chemical properties, density and pH of Xiaocuojiefu film were determined,and its main components, Chrysanthemum indicum L., Coptis chinensis Franch and Sophora flavescens Ait were identified by TLC.

A brief survey of the resources of fungi in Hunan Province used for medicinal purposes was carried out by studying their di stribution and cultivation.Their rational use and future pevelopment were briefly discussed.

Effect of Emodin (EMD) on free intracellular Ca2+([Ca2+]i) in peritoneal macrophages of mice was measured with Ca2+ sensitive fluorescent indicator Furi-2/A m quantitatively.Results showed that in the resting, [Ca2+]i level in the peritoneal macrophages was 198.56?44.82nmol/L (n=11) in Ca2+ free Hank's solution. After adding 0.75, 1.75 and 2.75 mmol/L CaCl2 to macrophages suspension sequentially, the free[Ca2+] levels were obviously higher as compared with that of the resting level (P

Paeoniflorin in antiaging Preparation was qualitatively identified with chemical and TLC methods and quantitatively determined with HPLC. The results showed both tne chemical and TLC method gave fast and accurate results and HPLC was an excellent for quantitative determination with an average recovery of 100.72% and coefficient of variation 1.22%, which is suitable for the quality control of the preparation.

Ultraviolet spectrophotomety was used to determine Tween-80 critical micell concentration (CMC) in different Chinese herbal medicine injections. Studies on the concentration of iodine solution and wavelength suitable for the determinntion were carried out. This method is quick and accurate and can be used for the quality control of such preparation.

Distinction between the traditional Chinese medicine amber and its counterfeit was studied by polarizing microscope and electron microscope, and trace clements analyse d by plasma spectroscopy. Results showed that the counterfcit of amber is opal, which contains the same thirty-five kinds of trace elements as coal amber. The total amount of Ca, Mg, Al,and Fe contained in opal is 10 to 70 times more than that contained in coal amber, whichcau provide a basis for the appraisal of coal amber and opal.

A survey on drug resources and identification or the commercial drugs showed that Heshouwu was derived from Polygonum multiflorum and the roots of another two species of the same family were misused as Heshouwu. The roots of 6 species of Cynanchum genus, Asclepiadaceae were used as Baishouwu in different regions. The index of botanical identification was listed. Botanical origins, distribution, production and sale of "Shouwu" were investigated.

A new disease of Rhubarb occured in Gansu Province of China was reported.The disease appears along the veins of lower leaf surface of Rhuaarb (Rheum palmatum) with swelling,and shows a reddish-purple color at the beginning and turns pale brown late. On the leaf appears yellowish reticulated sppts, in Petioles the spots are tumourlike blisters arranged in rows.The growth of the smaller and in severe attacks the whole plant eventually withered.The causal pathogen was identified as a smut Thecaphora schwarzmaniana and seems to be the first reported case that occurs in China.Methods for its control are suggested.

Snake compound (SC)consisted of the alcoholic extract of Zaocys dhumnades,Agkistrodon halys(Pallas)compounded with Chinese herbs: Astragalus membranaceus Bge. var. mongholicus (Bge.) Hsiao, Angelica sinensis (Oliv) Diels, Rehmannia glutinosa Libosch, Paris pollyphylla Sm. var. yunancnsis, Epimedium brevicornum Maxim and Salvia miltiorrhiza Bge.. Acute toxicity test showed that the maximum tolerant oral dose for mice was 120mg/kg, 1091 times higher than the dose used in clinic for patients. Analgesic and anti-inflammatory studies showed that the times of writhe induced by abdominal administration of acetic acid were decreased significantly and the pain thre shold of electrical stimuli was increased markedly by SC in mice. The analgesic effects were dose-dependent. Inflammatory swelling in digiti pedis of rats induced by carrageenin and swelling of ear in mice were alleviated dramatically by SC.SC showed good effects in the treatment of winddampness syndrome and anthralgia syndrome in clinic.
