Introduction: Insulin-dependent diabetes mellitus (IDDM) or type 1 diabetes is an organ-specific autoimmune disease that caused by destruction of insulin-producing beta cells of the pancreas. Etiology of this disease is still unknown. It is seen that genetic and environmental factors play an important role for susceptibility to develop type 1 diabetes. The relationship between HLA associated factors and susceptibility to IDDM disease, was reported by several investigators. Also, some studies show that dermatoglyphics is associated with type 1 diabetes. However, it is maybe there is an association between HLA and dermatoglyphics inpatients'with type 1 diabetes and these characteristics could be applied for diagnosis of disease.
Materials and Methods: In this study, the prevalence of HLA (with using standard microlymphocytotoxicity method) and dermatoglyphics determined in 30 Iranian patients with IDDM and 30 normal healthy controls with similar ethnic background and the same geographical area.
Results: A significantly higher frequency of HLA-DQ, A2, DR3 and DQ2 were found in IDDM cases compared to the controls. The results obtain from dermatoglyphics showed that line ab was reduced in male and female type 1 diabetes. The reciever operating chractristics curve showed that the positive point for lines ab in right and left hands were 34.7 and 35.25, respectively.
Discussion: There is no association between HLA and dermatoglyphics.
With considering of genes encoding of HLA separated from genes determining dermatoglyphics, HLA typing and dermatoglyphics seem to be interesting tools for genetic studies related to type 1 diabetes. Further studies are recommended in order to provide more insight into the susceptibility to this disorder.

Introduction: Diabetes  during  its  progress can  result  in  nephropathy.  Some  of  its  symptoms  are  increasing  kidney  size  and  weight  and  its  components.  Regarding  useful  components  of  onion  and  its  antioxidant, decreasing  stress  oxidative  and b decreasing  blood  glucose  effects. This  investigation  is designed  to  study  the  effect  of  onion  water-alcohol  extract  in  preventing  nephropathy  and  its  effect  on  kidney  structure  based  on  stereology  method.
Materials  and  Methods: Four  groups  of  matured  vistar  rats (n=8)  were  selected randomly (control  group, control + extract  group, diabetic  only  group, diabetic + extract  group). Diabetes  was  induced  by  injecting  interperitoneal  sreptozotocin  (60mg/kg). The  control+ extract group  and  diabetic + extract  group  were  treated  by  onion-water  extract (50 mg/rat)every day  for  four  weeks. Then  all  groups  were  anesthetized  and  their  left  kidney  was  removed  and  fixed  in  Bouin  fixative. After  histologic  passage  and H & E  dying, using  stereologic  techniques, qualitative  measurement  was  performed  by  Cavalier  method  for  cortex, medulla, glomerulus  and  kidney  size.  Data analysis  was  done  by  SPSS  software  using one  way  anova, tukey  and  paired  test. p<0.05  was  considered  significant.
Results: The  primary  and  secondary  weight  of  rats  in  only  diabetic  group  and  diabetic  + extract  group  was  not  different, but  in  control  group  and  control  + extract  group  was  significantly  different (p<0.05). Medulla, cortex  and  whole  kidney  size  in  only  diabetic  group  in  comparison  with  diabetic+ extract  group  had  no  difference, but  total  glomerular  size  in  diabetic  only  group  and  diabetic + extract  group  was  significantly  different (p<0.001).
Conclusion: Experimental  induction  of  diabetes  by  STZ  in  a  short  period  showed  that  onion  extract  can  prevent  glomerular  hypertrophy  and  increasing  kidney  weight  in  diabetic  rats, but  had  no  effect  on  overall  kidney  size. So  the  study  of  onion  extract  effects  on  kidney  structure  during  a  long  period  is  recommended.

Dermatoglyphic patterns are formed during the first and the second fetal development trimesters and they remain unchanged afterwards. At the end of the fourth month of fetal development, fingertips are formed along with brain and other derived ectodermia developments. In the 19th century, the mystery of human fingertips was discovered, and it was realized that fingertips consist of tiny network lines in the epiderms of the skin, and are exclusive to every individual, even to twins. In this study, through library research, by reviewing quantitative and qualitative dermatoglyphic patterns, the miracle of fingertips was considered based on Quran and Islamic commandments. Much research has been done comparing individual dermatoglyphic patterns of hands among various races, and the quantitative and qualitative relationship between dermatoglyphic patterns and diseases such as schizophrenia, nervous disorders, Down syndrome, diabetes I, Alzheimer, multiple sclerosis, congenital spinal abnormalities, and psoriasis disease has been shown. Accordingly, finger prints are used for identifying individuals, detecting criminals, and studying disease of genetic background. They can also be used as clues in determining the etiology of diseases. Fingertip sign is unique for every individual. Quran, in response to those who deny the resurrection after decomposition of the body and bones (Saffat, 37: 16), declares that Allah almighty, is not only capable of recreating them, but also is able to make human fingertips again (75: 3-4). The study shows the importance of human’s fingertips as the miracle of human creation, and reveals why Quran emphasizes on them as one indication of resurrection.

Background: Morphine is one of the derivations of opium alkaloids. Contradictory reports exist on hyperglycemic and hypoglycemic effects of morphine. The aim of this study was to evaluate the role of opioid receptors involved in blood glucose changes in morphine-treated Balb/c mice. Materials and Methods: This experimental study was carried out on 8 groups of male Balb/c mice (n=6), including group1(morphine), group 2 (naloxone (morphine antagonist) + morphine), group 3 (naltrindole ( receptor antagonist) + morphine), group 4 (norbinaltorphimine ( receptor antagonist) + morphine), group 5 (CTOP ( receptor antagonist) + morphine), group 6 (saline), group 7 (saline + saline), and group 8 (saline + morphine). Blood samples were obtained from retro-orbital sinus at 0, 1, 2, and 3 hours after injection. Blood glucose level was measured by enzymatic technique. Data were analyzed by SPSS software. Results: The application of morphine resulted in significant hypoglycemia in comparison with the control group which was significantly compensated by naloxone compared to the morphine group. The application of naltrindole could significantly inhibit hypoglycemia induced by morphine compared to the control group, whereas norbinaltorphimine and CTOP failed to do so. Conclusion: Since naltrindole could compensate for hypoglycemia due to morphine, hypoglycemia caused by morphine is likely to be mediated by opioid receptors

Background: Sodium arsenite has adverse effects on the reproductive system and vitamin E is a strong antioxidant and reproductive factor in the reproductive system. The aim of this study was to investigate the effect of vitamin E on the structure and the number of ovarian follicles during its development in rats treated with sodium arsenite. Materials and Methods: Pregnant Wister rats (n=4) were divided into 4 equal groups, including control, vitamin E (100mg/kg/day), sodium arsenite (8mg/kg/day), and sodium arsenite+vitamin E. Oral treatment of the pregnant rats started from the 7th day of pregnancy till the end of the weaning and continued till the age of 120 days. After the treatment period, the right ovary was removed and fixed, and then the mean number of ovarian follicles and atretic follicles, mean thickness of zona pellucida, and volume of oocytes and its nuclei in different types of follicle were determined. Data were analysed using one-way ANOVA and the mean difference was considered significant at P<0.05. Results: In the vitamin E+sodium arsenite group, significant increase(P<0.05) in the total number of follicles, mean number of primordial, primary, secondary, antral, and graafian follicles, significant reduction (P<0.05) in atretic follicles, and significant increase(P<0.05) in the thickness of zona pllucida in secondary and antral follicles as well as oocyte volume in parimordial and primary follicles and its nuclei in primary, secondary, antral, and graffian follicles were observed in comparison with the other groups. Vitamin E in the sodium arsenite+vitamin E group increased the number of different types of follicles and the thickness of the zona pllucida (P<0.05), decreased the number of atretic follicles, and increased the volume of oocyte and its nuclei to the level of the control group. Conclusion: Vitamin E can be administered as a supplement to compensate for the adverse effects of sodium arsenite.

Background: Prostate cancer is one of the most prevalent type of cancer and the second cause of death among American men. Its prevalence has a direct relationship with increasing age. The present study was carried out to determine the level of prostate specific antigen (PSA) and calcium level in blood in men with prostate cancer and BPH in Arak.

Materials and Methods: In this prospective study, out of 400 Arak males, were selected from different inner-city areas through cluster sampling during a period of two years (august 2011-august 2012). After the population was approved to have the necessary criteria to be included in the study, their PSA and calcium level was measured and its mean in over 40 years. In order to determine mean difference among the seven groups T-test analysis and to determine "PSA", PSA Assay and Tandem-R kits were utilized and for measurement of serum calcium, pars azmoon kit was used.

Results: In this study, there was a markedly relationship between age and serum calcium and serum PSA in both groups.in this way that there was a negative relationship between age and serum calcium and a positive relationship between age and serum PSA.

Conclusion: With respect to the findings of the study, it could be confirmed that was a markedly relationship between serum PSA and serum calcium only in prostatic cancer patients,according to this study in future maybe we used serum calcium as a tumor-marker for screening for prostate cancer.

Background: Bisphenol A (BPA) has estrogenic properties and generates reactive oxygen species (ROS). The aim of this study is to investigate the effect of Nigella sativa oil (NSO) on sperm parameters against toxicity induced with BPA.

Materials and Methods: In this experimental study, adult male mice with mean body weight 32±3 g were randomly divided into 4 groups (n=6) Control, BPA (200mg/kg/day), NSO (5ml/kg/day), and BPA+NSO. Oral treatment was performed till 34 days. After end of treatment, body and left testis weight were recorded and left caudal epididymis was also cut. Released spermatozoa were used to analyze sperm parameters such as motility, viability and abnormalities. Sperm chromatin quality was assessed. Data were analyzed with One-Way ANOVA.

Results: Body and testis weight showed no significant change in four groups (p<0.05). A significant decrease in the motility, viability and normal morphology of sperm (p<0.001) was found in BPA-treated mice compared to the control group. In BPA+ NSO group, NSO could significantly increas the mentioned parameters compared to the BPA group (p<0.05). BPA had no effect on the uncleus diameter of the spetmatogonia and sperm DNA integrity and histon-protamine replacement.

Conclusion: The results indicated that NSO could partially ameliorate Bisphenol A-induced toxicity on sperm parameters.

Abstract

Background: Silver nanoparticles are capable of inducing toxicity in living organisms. Silver nanoparticles can induce some effect in the liver. Thus silver nanoparticles, due to their wide spread effects, can also affect on hepatic, hematological, and oxidative stress factors. Ginger because of its powerful antioxidantal compounds can influence the toxicity effects of silver nanoparticles in different parts of the body. The aim of this study was to investigate the protective effect of hydroalchoholic extract of ginger on cytotoxic silver nanoparticles on enzymes, hematological parameters, blood oxidative stress markers, and hepatic apoptosis in Balb-c mice.

Materials and Methods: In this study, 48 rats of Balb-c race Syrians were selected and devided into 4 groups, each consisting of 12. They were treated for a period of 35 days; the first group (control) received distilled water, the second group received nano silver, the third group received ginger extract, and the fourth group received both nanosilver and ginger extract at the same time. Bleeding was done to measure hematological factors, liver enzymes, and oxidative stress; then liver tissue was removed for evaluation of apoptosis. Data were compared using SPSS software and one-way ANOVA.

Results: Enzymes AST , ALT , ALP, GGT and LDH as liver factors showed significant differences in the groups of the study. Hematological factors including of WBC , RBC , Hb , HCT , MCV, MCH , Plt , Lymphocyte  and  Monocyte showed significant differences in all the groups.

Of oxidative stress factors , only GPX showed significant difference between groups, while no significant difference was observed in other oxidative stress parameters in the blood. Changes in apoptosis showed significant differences in all groups of the study.

Conclusion:  Based on the findings the study ,silver nanoparticles with their side effects in different parts of the body can induce changes in various factors and enzymes. Ginger can compensate ,and modify to some extent these side effects. Such effectiveness of ginger can probably be due to its special ingredients.
