Chinese traditional dietary therapy is the result of traditional medicine and cookery in China, and of ancient origin and long development. It hold the function to regulate some physiological activities and improve personal nutritional status. According to it a nutritious liquor, a new type of the concentrated drink filled in ampule commonly used in China, for children was designed and manufactured, which composed of a variety of traditional medical foods. The experimental study confirmed that this liquor improves the food availability, immunological activity, the ability to look for food in perplexity in animals and the nutritional status of zinc in juveniles and children etc. The mechanisms of the functions of this new liquor was discussed and the prospective development of the combination of Chinese traditional dietary therapy with modern nutrition was proposed.

To study the effect of using a steel stainless intrauterine device(IUD) on the incidence of anemia and iron deficiency and thus to find a suitable way to prevent or cure it, the serum ferritin level of 176 women bearing such an IUD was determined (FER-IRON kit, Ramco laboratories, USA). As compared with the control group which was composed of 163 women having been performed with tubal sterilization, no distinct difference in hemoglobin levels and red cell counts was observed, but the serum ferritin level in IUD-bearing group decreased markedly (26.6?1.4 vs. 36.3?2.2 ng/ml, pears). When treated with ferrous sulfate (0.3 g, t.i.d.) for 7 days, the ferritin level of the group of these IUD users raised up to that of the control group rapidly. It was suggested that the supplement of iron in time for the IUD users suffering from menorrhagia was necessary and efficient.

astaxanthin is an effective antioxidant and natural pigment which has wide application. Phaffia rhodozyma is a good source of astaxantin, but wild strain has limited use in industry because of low production level of astaxanthin. Several mutants of Phaffia rhodozyma were obtained by exerting mutagen N-methyl-N-nitro-N-nitrosoguanidine. The growth curve suggested that pigments were mainly produced in the middle and latter periods of log phase. The pigments were extracted from Phaffia rhodozyma and analysed by esterification, thin layer chromatography and absorption spectrometry. It was proved that astaxanthin, astaxanthin diester and β-carotene were the major components of the pigments produced by Phaffia rhodozyma. We also studied the pigments producing phase of Phaffia rhodozyma. and founded that astaxanthin was stable to light under butylatedhydroxytoluene coexistance.

Microvascular architecture of the oviduct was observed by SEM in 20 adult female Wistar rats which were not pregnant. The oviduct was supplied by 2-4 tubal branches (0.2-0.3mm in diameter) which were derived from the ovarian artery. The tubal branches entered the wall of oviduct and divided into numerous meandering arterioles (0.02-0.07mm in diameter). Intrinsic microvasculature of the oviduct might be divided into three layers: (1) the subserosal vascular plexus which appeared tortuous and formed reticulate anastomosis, (2) a parallel branching vasculature in the muscle coat, and (3) the subepithelial capillary network. The latter arised from the arterioles which ramified terminally near the apex of mucosal folds and broke up into very dense capillaries. Subepithelial capillary density in the fimbriae was markedly higher than that in the isthmus and uterine part. Intrinsic venules of oviduct were less tortuous and less closely accompanied with the arterioles. In mesoviduct, veins were in closely accompanied with the corresponding arteries. In the wall of oviduct, some capillaries and venules drained to the small veins directly and vertically.
