large intestinal roundworm of swine
1.Clinical significance of DCC gene in reoperation of large intestinal cancer recurrence after radical operation
2.Comparative study of DCC gene status between primary and liver metastatic lesions of large intestinal cancer
3.Objective:To understand DCC gene status between primary and liver metastatic lesions of large intestinal cancer.
4.Objective To study the expressions of p16,cyclinD1,CDK4and anal-yse their significances in large intestinal cancer.
5.Objective: To study the relationship between DCC gene expression and recurrence and reoperation of large intestinal cancer after radical operation.
6.Methods: Immunohistochemistry and PCR- SSCP were applicated to detect DCC protem expression and DCC cDNA sequence muta-tion in 136 cases of large intestinal cancer recurrence after operation and 30 cases of primary and liver metastatic large intestinal can-cer.
7.The thesis mainly studied economy benefit, total inventories whose were Duroc breeding swine production system, Landrace breeding swine production system and Large Yorkshire breeding swine production system, structures of pig herds of three varieties, when pig breeding farm production system was steady, and the dynamic change ruler of breeding swine production system, when swine herds were changed suddenly, then conclutionswere as the follow:
8.intestinal volvulus
10.intestinal fistula
