This experiment was carried out with 30 growing pigs during a period of 14 weeks to examine the effects of additional levels of 0.1 and 3% of pine-needle meal on body weight gain. 1. The pig fed 1% pine-needle meal showed significantly (P $lt; 0.01) higher body weight gain. 2. Body weight gain of 3% was lower than that of 1%. 3. Effects of pine-needle meal was appeared at early stage of growing period. 4. Pine-needle meal adding by 1% is desirable for growth, economical value, disease control and feed efficiency.

This experiment was carried out to develop a chemical castration with a single intratesticular injection of silver nitrate solution in domestic rabbits. A total of 44 bucks of 4 to 5 months old were alloted at random into the following 4 groups: 9 bucks for controls, 6 bucks for 0.3㎖ injection of 1% AgNO₃, 14 bucks for 0.5㎖ injection of 1% AgNO₃ and 15 bucks for 0.5㎖ injection of 5% AgNO₃. Changes in body weight, testicular width in scrotum. weight and histology of testis at necropsy, blood cell counts and plasma levels of testosterone of the buck were measured for 4 weeks after treatment. The results obtained were summarized as follows: Compared with the controls, the body weight gain of bucks treated with AgNO₃ was not significantly (P$lt;0.05) different during the experimental period for 4 weeks. The white blood cell counts were tended to be increased slightly but insignificantly 1 day after injection of AgNO₃ and then decreased to normal level soon. There was no significant change in red blood cell counts in the bucks treated with AgNO₃. Most of the testis of bucks were swollen significantly (P$lt;0.05) by 6 to 12㎜ in the width of testis in scrotum 1 day after injection of AgNO₃, but began to decrease in sue from 3 days after treatment and to their normal size in a week. The AgNO₃ injection was not sufficient to castrate some bucks successfully. Only 60.0 to 66.7% of the bucks treated with 0.0㎖ of 1 or 5% AgNO₃ solution showed the plasma levels of testosterone of !sower than 0.1 ng/㎖ by 28 days after treatment. This result was considered to be due to the fact that not a whole but a limited part of testis was injured by the present method of injection. The weight of testis of the bucks of which plasma testosterone were less than 0.1 ng/㎖ by 7 to 28 days after treatment was not significantly(P$lt;0.05) different between the treatments or periods after treatment. This result indicates that the period of 4 weeks following treatment might be insufficient for the injured testicular tissue to be necrotized and absorbed fully. The extent of damage of testis by injection of AgNO₃ was much different by the local effect in the parts of distance from injection. The proximal portion of testis injected with AgNO₃ was fully damaged and necrotized, but a distal part of testis was not severely damaged.

Wegener`s grandulomatosis (WG) is a systemic small-vessel vasculitis characterized by necrotizing granulomatous lesions and anti-neutrophil cytoplasmic antibodies (ANCA). WG frequently affects the upper and lower respiratory tracts and kidney but involvement of the pachymeninges or large vessels has rarely been reported. We report the first case of WG with periaortitis and pachymeningitis in Korea. A 57-year-old female complained of a stabbing headache, paresthesia below the thoracic 4th nerve level, and lower extremity weakness. During her course, she developed otitis media with sensorineural hearing loss, nodular scleritis, and microhematuria. A neuroimaging study showed an intradural mass in the area from the cervical 7th spine to the thoracic 5th spine, left cerebral convexity, and the left petrous area. A chest computed tomography scan revealed an enhanced and thickened aortic arch. A dural biopsy showed necrotizing granulomatous inflammation, and anti-MPO ANCA was positive. Under a diagnosis of WG, she received high-dose glucocorticoid and oral cyclophosphamide with improvement.

Secondary amyloidosis (Amyloid A amyloidosis) occurs when serum amyloid S accumulates in various tissues and organs. It often accompanies chronic inflammatory disease, especially rheumatoid arthritis, as well as ankylosing spondylitis (AS) and Crohn`s disease. Although amyloid deposits were reported in 7% of the abdominal fatty tissue samples from AS patients, most of the patients had no symptoms. In a large study, 1.1% of 730 patients with AS were diagnosed with amyloidosis. Most of them showed renal involvement, while none had gastrointestinal symptoms. In South Korea, only a few cases of gastrointestinal involvement of secondary amyloidosis have been reported in AS patients, and there is no report on the effect of a tumor necrosis factor (TNF)-α inhibitor. We report a case of secondary amyloidosis in an AS patient who improved with the TNF-α inhibitor etanercept. (Korean J Med 2015;89:259-263)
