Case Reports[Experimental and clinical study of skin stored by vitrification].
To improve the quality of stored skin, vitrification storage method (rapid cooling) was introduced. G group cryoprotective solution (20% DMSO and 6% propylene glycol in kreb's Ringer phosphate solution) was selected from 7 different kinds of solution with low toxicity and high cryoprotective activity. G group solution was proved very effective in cryopreservation of small and large pieces of guinea pig skin. ⋯ The color of skin turned to red within 3-4 days after grafting. There was no blister formation on the surface of grafted skin. If autologous micro-skin were put underneath the stored skin or small pieces of autologous skin were inserted into the small holes of the stored skin, the wounds healed smoothly within six weeks after operation and no further grafting was needed.(ABSTRACT TRUNCATED AT 250 WORDS)

[Autogenous nerve replantation in situ for prevention and treatment of traumatic neuroma. Laboratory study and clinical application].
The median and ulnar nerves of 30 rabbits were surgically severed and replanted in situ on the right side, but a little segment was resected and left alone on the left side. Periodical examination of the specimen under light and electron microscopes in 24 weeks showed that in the replanted group (right side) the nerve fibers were regularly arranged in order with constant polarity, and the Schwann' cells were intact without signs of neuroma. ⋯ Follow-up examination within 6-48 months (32.6 mon. on average) showed good and excellent results in 90.0% the neuroma. Four different methods for repairing various neuromas were described, and the cause of the poor result in 2 cases was discussed.

In 100 patients with kyphosis who received wedge-osteotomy, Cobb's degree greater than 90 degrees was noted in 44, of whom 44 patients showed radiologically aortic calcification. Follow-up for more than 1.5 years showed an average correction degree of 57.2 degrees and an average correction rate of 77.2%. Body height increased on the average by 16 cm. We analyzed biomechanics of this operation.

Nineteen patients with infective endocarditis underwent surgery. Congenital heart disease was found in 6 patients, valve disease in 13. Seven patients had history of rheumatism. ⋯ There was no operative death. Follow-up for 3-109 months after operation showed no evidence of recurrent endocarditis. We suggest that early surgical treatment is mandatory for intractable infective endocarditis if excellent result is expected.

Neural blocking of phenol-glycerine was used for the treatment of cancer pain originated from the esophagus, stomach, liver, lung, rectum, ovary, nasopharynx, head and neck. According to the dose difference, 148 cases were divided into three groups of 7-10% 4-5 ml (30 cases), 15-20% 3-4 ml (70 cases), and 25% 2-2.5 ml (48 cases). The result observed among the three groups as good or fair was 46.7%, 80% and 89.6% respectively, however, complications occurred too within the rate of 13.3%, 34.3% and 14.6% respectively. It is indicated that 2.5 ml of 15-25% phenol-glycerine seems better.
