摘要
Degradation of luteinizing hormone releasing hormone (LHRH) in various pig tissues (i.e. buccal, liver, nasal and skin) and in their corresponding homogenates was determined. The degradation of LHRH followed apparent first-order kinetics. The degradation rates of LHRH in intact tissues were lower than in their corresponding homogenates. The lowest degradation rate [(0.15 +/- 0.01) x 10(3) min(-1)] was observed in intact skin tissue indicating that the skin has minimal proteolytic activity, thus decreasing the rate of LHRH degradation.
