Abstract
This study was conducted on 48 specimens of Rectus abdominis muscles for recognition and definition of passage and ramification of lower intercostal nerves. The main results of this study are as follows: 1- The seventh and eight intercostal nerves penetrated to posterior layer of the Rectus sheath while other intercostal nerves perforated to dorsal layer of internal oblique abdominis aponeurosis. 2- Distance between lateral border of the Rectus abdominis muscle till penetrate point for all nerves were 18±1 mm, but the subcostal nerve was 16±1 mm. 3- Each intercostal nerve was ramified in thickness of muscle and formed many branches that maximum of this was middle longitudinal region and minimum of that was lateral longitudinal region. In addition we did not observe the nerve anastomosis between intercostal nerves. 4- The lower primary branch of the intercostal nerve after piercing of anterior layer of the Rectus sheath was named anterior cutaneous branch and terminated to abdominal skin. 5- All of intercostal nerves at first was placed right angle to muscle fibers but immediately decrease its and was placed parallel to muscle fibers. 6- The entrance, passage and ramification of intercostal nerves in both male and female cadavers were similar.

Abstract
The medical septal area (MSA) provides the major cholinergic projection to the hippocampus which is critical for function of the memory. Different brain areas through the MSA modulates septohippocampal functions. This study was designed to determin origins of inputs to this area. For this purpose, stereotaxic injections of one microliter HRP (25 percent, Sigma) by Hamilton syringe to the medical septal area were performed in 8 rats. Following brain tissue fixation, sectioning and enzyme histochemical reaction, the labeled neurons were detected microscopically. Retrogradely labeled perikarya observed ipsilaterally in diagonal band of Broca, lateral septum, hippocampus, subfornical area and ventral pallidum in the telencephalon, lateral preoptic area, lateral hipothalamicarea/tuber cinereum, posterior hypothalamus, submammillothalamic, supramammillary and lateral mammillary nuclei in the diencephalons, ventral tegmental area, interpeduncular nucleus, central grey area and locus coerruleus and also bilaterally in raphe nuclei of the brain stem regions. Based on this results, in addition to learning processes, MSA through its connections with subfornical and lateral hypothalamic area can also support the physiological mechanisms for dipsogenic, electrolytic, and pressor responses in living animals.

Abstract
Background: Freezing and thawing induce a number of insults to the sperm cells, such as low motility and low fertilization capability. For evaluation of hyaluronan (HA) supplementation on sperm characteristics, we investigated the effect of hyaluronan (HA) on mouse sperm before freezing and after thawing.
Methods: For this purpose we removed cauda epididimes from 24 male mice with aseptic method and freezed the semen in 1.8ml cryotubes with %18 raffinose and %3 skim milk cryoprotectant solution.We had 4 groups: group 1(fresh control) group 2(freeze control) group 3(supplemented 750 µg/ml HA to sperm before freezing) and group 4(supplemented 750 µg/ml HA to sperm after thawing). Fertility rate evaluated after routine IVF by counting two-cell stage embryos.
Results: HA supplementation (750µg/ml) after thawing improved fertilization capability parameters but supplementation before freezing had no effect on mentioned characteristic.
Conclusion: Acording to data of present study the hyaluronan supplemen- tation (750µg/ml) after thawing has the greatest effect on the fertility rate of sperms.
