Out of 21 patients, 12 had done subtotal sacrectomy and the remaining 9 had done partial sacrectomy. Their follow-up periods were at least five years. Operative time ranged between two to four hours. All patients recovered well from operation and two to five units of blood transfusion were needed for each. After operation, majority of the patients developed some bowel and bladder dysfunction and five patients developed wound infection. During the follow-up, two patients had tumor recurrence and one patient expired two years after operation. The remaining 18 patients were tumor-free at the 5-years follow-up. Wide surgical resection via the posterior midline approach could be a good management plan for the sacral chordoma. However, complete removal with surgical margin varies according to the location of the tumor.

In this in vitro trial, collected semen from Black Bengal bucks was preserved at chilling temperature (4～5℃) in tris-glucosecitrate yolk medium of 1:5 ratios for four days. Artificial Vagina (AV) method was utilized to collect semen from buck. General evaluation of semen includes the color, mass activity and density were measured by direct visual examination. However, computer-assisted sperm analysis (CASA) and phase contrast microscopy were used to figure out the motility (%), hyper-activated (HYP) motility (%) and number of abnormal spermatozoa (%) initially, and at every 24 h intervals. The result revealed that spermatozoa preserved at chilling temperature showed significantly (P<0.05) lower motility and HYP motility with the progression of preservation. The number of phenotypically abnormal spermatozoa significantly (P<0.05) increased following preservation. Although significant positive correlation (r=0.945; P<0.05) was existed between % motile and % HYP motile spermatozoa however, the % of morphologically abnormal spermatozoa was negatively correlated with % motile (r=0.997; P<0.05) and % HYP motile spermatozoa (r=0.946; P<0.01). Therefore, we concluded that the quality of chilled semen progressively losses its viability and doesn’t remain useable after certain period of preservation with respect to its motility and morphology.
