The objective of this study was to compare clinical findings and inflammation indicator levels between total laparoscopic hysterectomy (TLH) and total abdominal hysterectomy (TAH) in an instructional setting.

In this prospective study, 80 total hysterectomy procedures were performed at the gynecology clinic of Imam Hossein Medical Center, Tehran, Iran over the period between January 2017 and October 2019. Patients were divided into two groups according to the type of operation. Forty patients underwent TLH (TLH group) and 40 patients underwent TAH (TAH group). Surgery-related outcomes and inflammatory mediators were both assessed before and 24 hours after the surgery. 

We observed significantly lower operation bleeding (P <0.001), postoperative lower c-reactive protein (CRP) (P <0.001), higher length of surgery (P <0.001), and higher anesthesia duration (P <0.001) in TLH group compared to TAH group. There were no statistically significant difference between groups regarding post-operation transfusion, adverse events, polymorphonuclear leukocytes (PMN) count, white blood cell (WBCs) count  and platelet (PLT) count, as well as the homoglubin (Hb) levels.

Our study results show that the TLH can be safely performed in our instructional setting and it decreases intraoperative bleeding and postoperative day one CRP levels compared to the TAH method.

The aim of this study was to compare the quality of bull sperm produced in 0.5 and 0.25 ml semen straws before and after freezing.

In this experimental study, semen samples were collected from 12 dual purpose Simmental (Fleckvieh) bull kept at Iran Simmental Cattle Breeding Center during a two-month period. Each ejaculate was divided into two equal portions. Then, the formulation and freezing processes were performed separately for each type of straw. Sperm qualitative characteristics, antioxidant and oxidant levels of frozen semen produced in bulls' 0.5 and 0.25 were compared.

The results showed that all sperm quality parameters in 0.25 ml straws were better than 0.5 ml before and after freezing. Catalase (CAT) activity was higher in 0.5 ml straws than 0.25 one, but it was not statistically significant. Malondialdehyde (MDA) levels were lower in 0.5 ml straws than 0.25 ml straws, but the differences were not statically significant. Moreover, no remarkable difference was observed in the activity of superoxide dismutase (SOD) activity enzyme.

Based on the findings of the present study and with the aim of reducing the production costs, it is recommended that bull sperm production centers and herdsman inseminators use 0.25 ml straws for semen freezing and cattle artificial insemination.
