ABSTRACT
Objective To determine the normal range of hematological and visceral weight parameters of F 1 4-week and 8-week old, male and female transgenic CB6F1 mice.The influence of gender and week age on the biochemical parameters was assessed .Methods 4-week and 8-week old CB6F1 mice, half male and half female ( n=20 in each group) , were weighed alive , dissected to weigh the main viscera , and blood samples were collected to test the physiological and biochemical parameters .Results When 4-week old and 8-week old CB6F1 mice were compared , there were significant differences in 22 parameters (body weight, heart, liver, spleen, left ovary, left testis, right testis, WBC, RBC, HGB, HCT, MCV, MCH, PCT, MPV, PDW, LYM, TP, ALT, ALB, P and TG) (P<0.01 for all), and in 8 parameters (left kidney, right kidney, right adrenal, thymus, left ovary, RDW, MON%and BUN) (P<0.05 for all). When male and female 4-week CB6F1 mice were compared, there were significant differences in 14 parameters ( body weight, heart, liver, spleen, lung, left kidney, right kidney, MCHC, LYM, ALT, ALP, GLU, P and CHO) (P<0.01 for all), and in 6 parameters (right adrenal, WBC, PCT, MPV, TP and BUN) (P<0.05 for all).For male and female 8-week old CB6F1 mice, there were significant differences in 15 parameters (body weight, heart, liver, lung, left kidney, right kidney, MCV, PCT, LYM, LYM%, NEUT%, ALT, GLU, P and CHO) (P<0.01 for all), and in 5 parameters (WBC, RBC, MPV, NEUT and TP) (P<0.05 for all).Conclusions The normal range of hematological and visceral weight parameters of 4-week and 8-week old male and female CB6F1 mice are determined.Our study establishes normal detection indexes of CB6F1 mice and provides useful reference for its application .
ABSTRACT
Objective To measure the organ weights , blood physiological and biochemical parameters of KK /Upj-Ay/J.Methods KK/Upj-Ay/J mice at five and ten weeks of age were selected , and the organ weights , blood physiological and biochemical parameters were observed .Results Parts of the organ weights , blood physiological and biochemical parameters of different ages and sexes were significant differences .The fasted blood glucose of KK/Upj-Ay/J mice reached 7.0mmol/L at 10 weeks of age .Conclusion The results show that the organ weights , blood physiological and biochemical parameters are affected by age and gender of KK /Upj-Ay/J mice.The fasted blood glucose reached the diabetes level at 10 weeks of age .
ABSTRACT
Objective To measure the organ weights , blood physiological and biochemical parameters , and immune function of Specific Pathogen Free ( SPF) Rag2 knockout ( KO) mice.Methods Rag2 knockout mice were selected at five and ten weeks , and the organ weights , blood physiological and biochemical parameters were observed .The percentages of CD3+, CD4+, CD8+, CD19+, B220+, NK1.1+, and CD11b+were checked by FCM in Rag2 KO mice at six week of age in terms of its T , B lymphocyte function and NK cell activity .Results Among the same sex group of NOD/SCID mice, the weights of brain, lung, spleen, liver, heart, kidney, and the levels of TBIL, WBC in 10 weeks of age are higher than 5 weeks.At the same age, the weights of heart, kidney, liver, spleen, and the levels of AST, ALP, A/G, GLU, PLT, PCT, WBC, and LYM%in male mice are higher than females.The Rag2 KO mice lacks T cells(0.36 ±0.15)%、CD4+T cells(0.21 ±0.06)%、CD8+T cells(0.23 ±0.07)%、CD19+B cells(0.28 ±0.04)%、B220+B cells(2.03 ±0.42)%).The percentage of NK cells is(24.13 ±3.62)%, and the percentage of granulocytes is (57.20 ±3.85)%.Conclusion The study suggests that the organ weights , blood physiological and biochemical parameters are affected by age and gender in Rag2 KO mice, which main biological characteristics are similar with C 57BL/6J mice.The Rag2 KO mice show the deficiency of T , B cells function .
ABSTRACT
