Anthropometric dimensions are basis for evaluation of newborns’ health. In respect of importance of anthropometric indices of head and face in forensic medicine, surgery, pediatrics, medical imaging, … . We achieved this study. Determining range of head and face dimensions in normal one-day old female newborns on Fars and Turkman races. This descriptive and cross-sectional study is achieved on 423 normal one-day old newborns (Turkman group: N=211, Fars group: N=212) by classic cephalometry method. Mean and standard deviation of cephalic and prosopic indices in Fars group were 78.63±4.7, 74.3±11.5 and in Turkman group were 77.85±8.7, 81.6±9.8 respectively. Dominant and rare types of heads in Fars group were mesocephalic (42%) and hyperbrachycephalic (9%) and in Turkman group were mesocephalic (39%) and hyperbrachycephalic (8%) respectively. Dominant and rare types of face in Fars group was hypereuriprosopic (71%) and hyperleptoprosopic (4.24%) and in Turkman group were mesoprosopic (39%) and hyperleptoprosopic (1.89%) respectively. This study determines the types of head and face in normal female newborns in Fars and Turkman groups and determines the effects of racial factor on the diversity of head and face shapes in normal newborns.

Gastro-enteritis due to Vibrio Cholera was increased suddenly in summer of 1998 in our country. In this research we studied epidemiological and clinical features of Cholerae patients. Vibrio Cholera isolated from 189 (3.3%) patients from 56II stool samples. 182 (96.2%) Vibrio Cholera O1 isolated. 46 (24%) patients with positive stool cultures for Vibrio Cholera were hospitalized. 50% patients were 15-45 yrs. No sex predominency was seen. The important observations in this study including: Fever in 28.1% (13) of patients, sever leukocytosis in 15% (7) of patients, RBC in stool in 33% (15) of patients. Fever and neutrophilia and RBC in stool probably shows co-infection with order intestinal pathogens or different serotypes of Vibrio Cholera with new characteristics. So we are recommending extensive research to be done on serotyping of all of the isolates of Vibrio cholera and other intestinal pathogens simultaneously.

Background and Objective: Estradiol plays an important role in folliculogenesis and its developmental stages of embryo. This study was done to determine the quantitative assessment of mouse embryo development yielded from in vitro fertilization of ovulated mature oocytes after ovarian stimulation using human menopausal gonadotropin (HMG) and Estradiol valerate (E2). Materials and Methods: In this experimental study, 40 female NMRI mice were allocated into two groups. Control and treatment groups received HMG alone (10 IU/mouse) and a combination of HMG and E2 (1μg/mouse) in single dose manner, respectively. Following the induction of ovulation by HCG, the oocytes collected and morphologically evaluated. MΙΙ oocytes for in vitro fertilization (IVF) were transferred into medium containing capacitated and incubated sperm derived from male NMRI mice. The yielded embryos subsequently transferred into developmental medium for reaching to the blastocyst stage. Results: The difference between the mean percentage of yielded oocytes and healthy MII oocytes in the control and treatment groups was not significant. The percentages of the fertilized oocytes reached to two-cells was 34.22±21.87 and 36.83±20.68 in control and treatment groups, respectively. The percentages of the blastocys stages of embryos was 49.41±26.5 and 62.02±30.11 in control and treatment groups, respectively. Conclusion: The addition of estradiol to HMG as an ovarian stimulator can not increase the rates of yielded MII oocytes and embryonic development.

Background and Objective: Granulocyte colony-stimulating factors (G-CSF) and its receptor express in developing follicles, fetal and reproductive tissues. The serum G-CSF concentration significantly increases during the ovulatory phase in comparison with other phases, so G-CSF may have an important role in ovulation and the early cross-talk between mother and conceptus in both human and animal models. This study was done to evaluate the Effect of exogenous G-CSF on ovulation and pregnancy rate in NMRI mice.

Methods: In this experimental study, 40 mature female and 10 male NMRI mice were randomly allocated into the control and treatment groups. All Ovaries were stimulated with intraperitoneal injections (IP) of 10 IU PMSG and after 48 hour by 10 IU hCG per mouse. The treatment group were recieved G-CSF (50mg/kg i.p.), at the time of PMSG administration, while the control group had the same volume of normal saline instead of G-CSF at the same time. 16-18 hours post-hCG administration, twenty female mice of both groups were sacrificed by cervical dislocation and ovulated oocytes were assessed. On day 16 post coitus, the rest of female mice of both groups were scarificed for withdrawing their fetuses to determine the effect of G-CSF on pregnancy rates.

Results: The ovulation rate in the treatment group (18.5±1.25) were significantly more than that of control (12.1±1.32) (P<0.05). The number of fetuses had no significant difference between control and treatment groups.

Conclusion: This study demonstrated that exogenous G-CSF may affect on folliculogenesis and ovulation but the following pregnancy outcome was not impressed.

Background and Objective: Gestational diabetes mellitus (GDM) is usually a disease caused by inadequate insulin production in pregnant women. GDM induces abnormal fetal growth.This study was done to evaluate the BMP2 and BMP4 genes expression in the development of the embryos heart in induced gestational diabetes of C57BL/6 mice.
Methods: In this experimental study, 8-week old adult C57BL/6 mice were randomly divided into diabetic and control groups. After mating of animals, the dams in diabetic group were received a single dose of 150 mg/kg/bw of streptozotocin on gestational day 1 of pregnancy, intrapereatonally. After 11.5 days of pregnancy, the embryos of both groups were extracted and heart tissue was extracted. RNA total tissue of the heart was extracted by trazole. After extracting RNA, expression of BMP2 and BMP4 genes in the heart of both groups was estimated by Real-time PCR.
Results: There was no singnificant diference in expression of BMP2 and BMP4 genes in the heart of 11.5 days of embryos in gestational diabetes mellitus group and control group.
Conclusion: Gestational diabetes mellitus had no effect on the expression of BMP2 and BMP4 genes in the development of the embryos heart.

Background and Objective: Gestational diabetes (GDM) is a metabolic disorder which is caused by insufficient secretion of insulin. GDM is a risk factor for embryo during pregnancy and it is possible leads to congenital heart defects (CHD). Some of these defects may be due to a change in the expression of some of the important structural genes in the heart. Desmocollin 2 and collagen structural genes have important role in the cell adhesion of the cardiomyocytes.This study was done to determine the effect of gestational diabetes on expersion of desmocollin 2 and col5a2 structural genes in C57BL mouse embryo heart.
Methods: In this experimental study, 12 adult female and six adult male C57BL mice were used.After mating of the animals and observation of the vaginal plug, the female mice with vaginal plug were randomly divided into diabetic and control groups. At the first day of pregnancy, Induction of gestational diabetes mellitus in dams in the diabetic group was performed by the intraperitoneal (IP) injection of Streptozotocin with a dose of 150 mg / kg body weight per day in GD1. While in the control group, only citrate buffer was injected.Cesarean Surgery was done at E11.5 and embryo's heart was extracted from the body.Extraction of RNA, cDNA, and quantitative measurements of the amount of RNA were performed using Real -Time PCR.
Results: Induction of gestational diabetes increased the expersion of desmocollin 2 and col5a2 structural genes in compared to controls, althought only the expersion of desmocollin 2 gene was significant (P<0.05).
Conclusion: We suggest that the induction of DM lead to upregulation of structural genes primarily including desmocollin 2 and col5a2 in embryos heart development.
