Baby cake'' is a kind of baby food which has been traditionally used in certain parts of China. It consists half of rice powder and half of flour. The lysine is the first limiting amino acid of "baby cake'' and it is also deficient in calcium.In order to improve the nutritional value of "baby cake", we enriched it with 0.25% lysine and 0.122% calcium.72 Wistar derived rats were devided into 3 groups: group A was fed with "baby cake" enriched with 0.25% lysine, group B enriched with 0.25% lysine and 0.122% calcium and group C with original "baby cake" as control.The results revealed: body weight, weight and length and density of bones all were better in enriched groups and the best was in the group enriched with lysine and calcium. All were statistically significant.

Objective To observe the location of the watershed zones of the choroidal blood supply relative to the optic disc in glaucoma by indocyanine green angiography, and to investigate the mechanisms in the development of glaucomatous neuropathy. Method Simultaneous ICGA and FFA were performed on 31 eyes of 31 patients with glaucoma (17 of POAG, 14 of NTG) and 37 eyes of 37 control subjects. The watershed zones were classified into three types according to their location relative to the optic disc: by type Ⅰ, no watershed zone around the optic disc; type Ⅱ, the optic disc surrounded partially by watershed zone; type Ⅲ, the optic disc surrounded completely by watershed zone. Each of the watershed zone types was scored (i.e., type Ⅰ=1, type Ⅱ=2, type Ⅲ=3). Results In 87.1% of the glaucomatous eyes, the watershed zones included or partially included the optic disc. However, the figure in the control group was 56.8%. The glaucoma group had a higher score of watershed zone type than the control group. Conclusions The mechanisms in the development of glaucomatous neuropathy are correlative to the choroidal blood supply around the optic disc.

This infant cereal chiefly consisted of rice meal, fullfat milk powder, rice germ and dried yeast, and fortified with ferrous lactate and calcium carbonate. This mixture contained 14.1% protein, 8.6% fat, 64.3% carbohydrate, 750mg% calcium, 10mg% iron, 1.0mg% zinc and proper amount of various kinds of vitamins.1. Growth test; 84 weaning SD rats were randomly divided into 6 groups:(A) Infant cereal group;(B) Control I; (C) Control II; (A') Infant cereal group; (B') Control I; (D) Casein group. The latter three groups contained 10% protein which were designed for calculating PER. All these different preparations were fed to 6 groups for 4 weeks. The results showed that the body weight gain, the FE, CE and PER were not significantly different between group A and B but there were significant difference between group A and C. The Hb was increased from 11.76g% ( ) and 11.46g%() to 14.30g% and 14.46g% respectively in group A. The bones developed well and no decalcification occured.2.Nitrogen balance test:(A). Infant cereal group; (B) Control I. The results indicated that the TD, BV and NPU of group A were 98.08%, 85.73% and 84.09% and of group B were 97.81%, 87.51% and 85.59% respectively. Both groups obtained the results of positive nitrogen balance, no significant statistical difference. The contents of hepatic and body nitrogen of two groups were also not significantly different.These data demonstrate that this infant cereal is able to promote the growth of weanling rats, to retain positive body nitrogen and to prevent the occurrence of anemia and rickets.

Objective To study the changes of hematological indices of blood donors after 400ml whole-blood donation.Methods Blood specimens of 123 healthy donors were collected before donation,1 day,7 days,1 month,and 3 months after donation.The dynamic changes of WBC,RBC,hemoglobin,hematocrit,Plt,plasma total protein,albumin and blood serum iron were observed.Results After donation,the changes of WBC,Plt,total protein of blood plasma and albumin showed no significant change.The levels of RBC,hemoglobin,hematocrit and blood serum iron returned to normal after 3 months.Conclusion For anyone who meets the health standard of blood donors,to donate 400ml whole blood at 3-month interval is harmless.

0.05);Single factor analysis showed that,8 factors such as planned pregnancy,gender expectation of mother and father of spouses,relation of primiparas with mother and father of their spouses were independently related to depression in spouse of primiparas;multiple stepwise regression analysis revealed that,social support,books and media with postpartum health care knowledge,gender expectation of mother and father of spouses were main factors that related to stress in spouses of primiparas(?=-0.68,-0.15,-0.13).Conclusion:Spouses of primiparas experience the same medium-leveled stress as primiparas.The related factors were multifold and the main factors were social support,books and media with postpartum health care knowledge,gender expectation of mother and father of spouses.

To compare immunological characteristics of Extracellular fibrinogen-binding protein (Efb) and Clumping factor A (CfA) of Staphylococcus aureus, we constructed two prokaryotic expression vector pET28a-Efb and pET28a-ClfA. After prokaryotical expression and purification, Efb and ClfA were used to immunize experimental animal. After the second immunization the antisera were collected and the antibody titers, the bacteria binding activity and adhesion inhibition activity of these antisera were detected by enzyme linked immunosorbent assay, adhesion inhibition assay and challenge. Both Efb and ClfA had Fibrinogen binding activity whereas the former had better Fibronectin binding activity. The bacteria binding capability of antisera of rabbits immunized with ClfA was better than that with Efb (P < 0.01). Both antisera of Efb and ClfA could inhibit adherence activity of Staphylococcus aureus to Fibrinogen and Fibronectin adherence compare to the control group (P < 0.01), and Efb had better adhesion inhibition activity than ClfA. The antibody titer of immunized group could reach 1:40 500. After the second immunization, both Efb and ClfA had good protective efficacy. This result constitutes a good foundation for Staphylococcus aureus subunit vaccine development.
