    ABSTRACT: INTRODUCTION Diabetes is a complex and multifarious group of disorders characterized by hyperglycemia (1). Diabetes is associated with increased risk of disease such as neuropathy and cardiovascular disorders, but it is also linked to reproductive problems such as spontaneous abortion, neonatal morbidity and mortality, congenital malformation and poor embryo development (2, 3). Diabetes causes alterations in the estrous cycle, associated with modification in gonads function in spermatogenesis and oogenesis phases, which induces a decrease of primordial germ cells (3, 4). Some chemical drugs such as biguanides and sulfonylureas are currently available to reduce hyperglycemia in diabetes mellitus (7). These drugs have side effect and thus search for new drug or new compound is essential (1, 8). Many herbs and plant products have been shown to have hypoglycemia action. This leads to increasing demand for herbal products plant with antidiabetic activity and lower side effects (9, 12). Aloe vera is one of these antidiabetic plants (13). This plant has stiff gray-green lance shaped leaves containing clear gel in a central mucilaginous pulp. Clinical evaluations have revealed that the pharmacologically active ingredients are concentrated in both the gel and rind of Aloe vera leaves (14). Polysaccharide containing plants which Aloe barbadensis is also among are used in various diseases as anti-inflammatory, antiulcer, antineoplastic and in wound healing and against hepatitis(15). It is known that it is activating macrophages and has also antiviral effect (16). In some studies it is shown that Aloe has an antioxidative effect. Its antigenetoxic and chemopreventive effect are also proven (14). The level of blood glucose was significantly decreased after oral administration of ethanolic extract of Aloe vera gel in STZ-induced ABSTRACT Objectives: Gonads are important organs of reproductive system and it's influenced in diabetes. Most of protective plants correction of hyperglycemia, Aloe vera has hypoglycemic effect. Thus, in present study, its aloe vera effect on gonads development of offspring of diabetic rats in gestational age during. Material and methods: Thirty of female Spraguedawely ratswere injected by streptozotocin (50 mg/kg/IP) and randomly divided to three groups, and then mating by male rat, vaginal plaque is objected. One group of rats receive aloe vera extract (400mg/kg) and other groups of rats take glibenclamid (5mg/kg) and giving distilled water another by oral in gestational age during. On day 30after birth, offspring rats sacrificed by ether solution. After dissect, testis and ovaries remove and fix by 10% formalin solution.Then, tissues were processed and embedding by paraffin. The 5 µ sections were made and staining by hematoxyline-eosin. Testis and ovaries structure change is evaluated. Results: Mean body weight , Mean blood sugar, means of seminiferous tubules diameter, Spermatogonium numbers, Leydig cells and Sertoli cells were difference significantly (P<0.05). Mean of cortex to medulla ratio, Primordial, Primary and Secondary follicle numbers and Primary and Secondary follicle diameter were difference significantly (P<0.05).Conclusion: Present study indicates that Aloe vera extract during gestational age can inhibit diabetic and repairing gonad process.

    ABSTRACT: Otostegia persica extract was used as a traditional medicine for the management of diabetes mellitus in humans in some parts of Iran. This study investigated the effects of O. persica oral extract on pancreatic beta cells in streptozotocin-induced diabetic rats by stereological methods. Thirty-two matured normoglycemic male Sprague–Dawley rats, weighing 180–220 g, were selected and randomly divided into four groups: Control group consists of normal rats which did not receive the extract during the study. Diabetic group comprises diabetic rats but did not receive any extract. Treated control group rats were normal but received the extract at a dose of 500 mg/kg/day. Treated diabetic group (TD) was made up of diabetic rats and received the extract (500 mg/kg/day). Diabetes was induced by a single intraperitoneal injection of 50 mg/kg of streptozotocin. After 1 month, all the rats received deep anesthesia with ether, and then, the pancreas was dissected and processed. Isotropic uniform and random sections were obtained by orientator method. Volume of pancreatic beta cells and also volume density of pancreatic island were studied, using stereologic and ultrastereological methods. Blood glucose level (BGL) and blood insulin level (BIL) were measured in different phases during the investigation. Statistical analysis by one-way analysis of variance test showed the presence of hypertrophic changes in the volume of the remaining beta cells in diabetic group, not in the controls. But such changes reduced significantly (P < 0.05) in the TD group which received the extract. Also, a significant reduction in pancreatic islet volume in diabetic and TD groups was seen, in comparison with the controls (P < 0.01). BGL decreased significantly in TD group, compared to the diabetic group (P < 0.001). BIL decreased in diabetic and TD groups in comparison to the controls (P < 0.05). This study demonstrated that O. persica oral extract can play an effective role in the management of diabetes and probably by controlling the hyperglycemic condition and not stimulating the beta cell to increase insulin secretion can help prevent to a large extent the entering of the remaining beta cells to some pathologic changes, like hypertrophy.

    ABSTRACT: The vertebral level of termination of the spinal cord was determined during postnatal life of male camel. Observations showed that termination of the spinal cord varies with the age of animal. In new born animals upto one month age, the spinal cord terminated at third sacral vertebra, while in one year old, mostly within middle and caudal third of second sacral vertebra and rarely within cranial third of third sacral vertebra. In 2.5-3 years old animal, the termination of spinal cord was at the level of middle third to caudal third of second sacral vertebra and then with the advancement of age at 4-6 years, it was terminated in middle third to cranial third of second sacral vertebra and beyond the age of 7 years upto 10 years mostly in cranial third of second vertebra. Therefore, it can be concluded that, the conus medullaris was preceded from caudal third of third sacral vertebra at neonate while in adult stage to cranial third of second sacral vertebra.

    ABSTRACT: Introduction: In pregnant mothers, maternal diabetes occurs when pancreas can't produce enough insulin resulting in increased blood glucose levels in the mother and subsequently in the fetus. This investigation was conducted to evaluate the effects of maternal diabetes on cerebellum of offspring of diabetic mothers (ODM), which was carried out at the veterinary faculty of Shiraz University in 2007-2008. Methods: This was an experimental study that included sixteen normal adult female rats divided in two groups. Diabetes was induced in one group by Alloxan agent. Both groups became pregnant by natural mating . At 7, 14, 21 and 28 days after birth, the cerebellum of all offsprings were collected and the weight of neonates was also measured. After producing histological slides, Olympus BX51 microscope and ‍‍‍‍‍‍‍ Olysia softwarwere used. Various histological parameters used included gray and white matters thicknesses (µ), the number of cells in gray and white matter separately per unit and the ratio of gray matter to white matter. Results: Cerebellar parameters decreased in ODM as compared to the control group. The body weight of ODM was significantly more than that of the control group (p< 0.05). Conclusions: Maternal hyperglycaemia exhibited deleterious effects on cerebellum during fetal life, which remained persistent during postneonatal period. Maternal diabetes also resulted in reduction of number of cells and thicknesses of both gray and white matter.

    ABSTRACT: This study was conducted to evaluate the effects of maternal diabetes on fetal spinal structure, especially in brachial enlargement. Sixteen adult female rats were divided into two groups. Diabetes was induced in one group by alloxan agent. Both groups became pregnant by natural matting. On days 7, 14, 21 and 28 after birth, the brachial enlargement of the spinal cord was collected from offspring of all rats and the weight of neonates was measured. Various histological parameters were determined using histological techniques. The results revealed a significant decrease in transverse spinal diameter and number of neurons of gray matter and an increase in vertical spinal diameter in spinal cord of offspring of diabetic mothers (ODM) as compared with the control group. The body weight of ODM was significantly more than that of the control group (P<0.05). Maternal hyperglycemia exhibited deleterious effects on spinal cord, especially brachial enlargement during fetal life which remained persistent during postneonatal period.
