STUDY OF MORPHOLOGICAL CHANGES OF HEART IN VIRAL MYOCARDITIS CAUSED BY REPETITIVE INFECTION OF CVB3m

Objective To investigate the morphological changes of heart in viral myocarditis caused by repetitive infection of CVB3m. Methods 4-week-old mice were infected four times intraperitoneally with a timedependent dose and killed at the 10th, 30th and 60th day after the final infection respectively, then we examined the heart changes and collagen hyperplasia by HE, VG stain and 1HC. Results Heart damage appeared very serious at the tenth day, even there were small necrotic foci at the day of 30th, but we could not see any injury of heart 2 months later after final infection. Collagen turned up at the tenth day and there was much more collagen in heart and increased PCVA, CVF index at the sixtieth day. The 1HC of collagen demonstrated the collagen I hyperplasia was much obvious compared to collagen Ⅲ. Conclusion It strongly indicated that repetitive infection of CVB3m could lead to heart fibrosis and ventricular remodeling, which resulted in decreased systolic and diastolic function of heart.

ISCHEMIC PAPILLOPATHY AND CONTRACEPTIVES

In January and again in April 1985, a 30-year old woman received 150 mg injections of Depo-Provera for contraception. 3 days after the 2nd injection, she experienced blurred vision in both eyes and was diagnosed as having bilateral papilledema. Her vision improved after treatment with vitamin B1 and other drugs. But optic atrophy of the right eye and papilledema of the left eye remained. In July 1985, after an injection with Depo-Provera, her vision again worsened. The woman received no more Depo-Provera after this time. In early 1987, she was referred to Beijing's Tong Ren Hospital, where she was diagnosed as having bilateral ischemic papillopathy and optic atrophy. There have been few documented cases in medical literature of ocular complications related to use of contraceptives. In 1981, Petursson et al. reported a case of macula edema resulting from oral contraceptives. In animal studies, oral contraceptives have been linked to papilledema and retinal vein obstruction. The case reported here is the 1st to link use of Depo- Provera with ocular complications.
