Length-weight relationship and condition factor of the mangrove crab Ucides cordatus (Linnaeus, 1763) (Crustacea, Brachyura, Ucididae)

The relationship of wet weight (WT) to cephalothorax width (CW) and temporal and seasonal variations in the condition factor were analyzed for each sex of the mangrove crab Ucides cordatus, using specimens collected monthly from September 1998 through September 2000, at Iguape, state of São Paulo. The WT/CW relationship, determined by the regression analysis and the condition factor were evaluated individually, monthly and seasonally, for each sex. The WT/CW relationship indicated isometric growth in males and negative allometric growth in females. Body weight was higher in males than in females of equivalent size and this difference was associated with the males' faster growth and heavier chelipeds. On the other hand, the means for condition factor were always higher for females than for males; the mean condition factor was lower in spring and summer and higher in autumn and winter.

A determinação da relação do peso úmido (WT) pela largura cefalotorácica (CW) do caranguejo U. cordatus e a análise da dinâmica temporo-sazonal do fator de condição foram realizadas com machos e fêmeas coletados mensalmente no período de 1998/2000, em Iguape (SP). A relação WT/CW foi determinada por análise de regressão, enquanto o fator de condição foi determinado individualmente para cada animal, bem como pela média mensal e sazonal para cada sexo. A relação WT/CW evidenciou um crescimento isométrico nos machos e alométrico negativo nas fêmeas, indicando que os machos atingem um peso corpóreo superior ao das fêmeas para um mesmo tamanho de referência. Tal fato está associado ao maior crescimento e peso dos quelípodos do macho. As médias do fator de condição das fêmeas foram maiores que as dos machos. Os menores valores do fator de condição ocorreram durante a primavera e verão, atingindo os maiores níveis durante o outono e inverno.

Nutritional status, morbidity and weight increase level of pregnant women in VinhBao district, HaiPhong city the year 2001

In Vinh Bao district, Hai Phong city in the year 2001, 825 female subjects aged 18-35 years old with first pregnancy or one child, without abortion or immature delivery, were divided into 2 groups according to BMI (For CED group: BMI < 18.5 and normal group: BMI  18.5). The prevalence of chronical energy deficit (CED) before pregnancy was 29%, among them, 1st grade CED 21.2%, 2nd grade 6.3%, 3rd grade 1.5%. The prevalence of common diseases (cough, fever, headache, diarrhoea…) in CED - 40.2%, higher than normal group - 26.3%. In general, for both two groups, morbidity reduced progressively in the course of pregnancy: the prevalence was 18.6% in the first trimestre, 8.8% in the second trimestre and 8.4% in the terminal 3rd trimestre. Considering body weight, in the first trimestre the weight gained by 0.48kg (CED group: 1.19lg, normal group 0.19kg), in 2nd trimestre, the weight gained 2.46kg (CED group 2.91kg, normal group 2.28kg), in the last 3rd trimestre 4.08kg (CED group 4.28kg, normal group 4.0kg).

Experimental study on progestogen activity of triphasic contraceptive tablets / 中国药理学通报

Aim To study the progestogen effect and activity of triphasic contraceptive tablets.Methods The progestogen activity of triphasic contraceptive tablets (kalirui and trinordiol) was evaluated through uterus weight increase test of female young mice and endometrium translation examination of female young rabbits. Radialized receptor analysis was used to determine the effect of the triphasic contraceptive tablets on progestogen receptor by the uterus histiocyte from the adult female rabbits whose ovaries had been taken away a week ago. Results Compared with the negative control, triphasic contraceptive tablets kalirui andtrinordiol in three phase groups not only enhanced uterus weight of female young mice, middle and high dose groups obviously accelerated the uterus weight increase ( P
