An analysis of the primary T wave changes in the electrocardiograms or l,509 cases of coronary, myocardial and neurotic diseases is reported. It seems that certain characteristics peculiar to each of the above-mentioned diseases do exist. Familiarity with these characteristics may help in differentiating these conditions clinically.

When certain bone tumors require the removal of an entire segment of the mandible, autogenous bone immediate grafting after mandibular resection is a widely accepted technic in current maxillofacial bone surgery. The rib and iliac crest are generally considered to be the best materials for this purpose. But the disadvantages of these approaches are obvious. The author proposes the use of autogenous boiled tumor bone instead. Using the author's technic operations were performed upon 5 patients with various mandibular tumors. Four cases achieved wound healing at first intention. In 1 of these new bone formation was revealed on radiagraphs and normal mandibular function was restored. The other 3 cases showed no sequelae at short-term follow-up. Analysis is made of the causes of the 1 failure. The technic of autogenous boiled tumor bone immediate grafting is briefly described and its advantages are evaluated. The author feels that use of boiled autogenous tumor bone instead of autogenous fresh bone is feasible in selected cases, including malignant tumor.

Laser, mainly the CO2 device, has been used in the treatment of ENT diseases, including chronic rhinitis, epistaxis, superficial localized angioma, nevus and wart, with good results. Laser therapy in tonsillitis and malignant tumor has also been satisfactory.

Progeria is a rare disease of unknown etiology, characterized by dwarfism, premature senility and early death. This report presents a case of progeria in Beijing. The patient, a girl, now aged 15, was a premature infant. The clinical and X-ray appearance is characteristic. The clinicoradiologic diagnosis of progeria is not difficult, if one keeps this disease in mind.

52 cases of acoustic neurinoma operated on during the years 1973-1974 are reported. The results of operation performed under either general anesthesia or acupuncture anesthesia with 3 different approaches are analyzed and compared. The lateral suboccipital approach with acupuncture anesthesia is considered to be the method of choice for removal of this tumor. The technics for the 3 approaches are described in detail with illustrations.

This article reports the successful in vitro cultivation of 465 Ancylostoma duodenale and 193 Ancylostoma caninum with 7 kinds of media of which the serum of young dogs was considered the most satisfactory. It was most favorable for hookworm rapid growth, oviposition, longer survival and increased copulation. Observations were made on the physiologic features of worm egg-laying, copulation and growth. It was found that in vitro young worms survived much longer than adult ones. Three young Ancylostoma duodenale survived for more than 200 days. The important factors affecting cultivation were: The selection of proper culture media, the pH of the selected media, bacterial contamination and temperature of the culture.

This paper reports 163 cases of intra- and ex-trahepatic choledocholithiasis treated by nonoperative general attack therapy (GAT) using combined traditional Chinese and Western medicine from 1971 to 1976. The results were encouraging in 70% of the cases. Stones expelled were found in the stool or loss of stone shadows was recorded on cholangiograms in 64.4%, and in 26.6% the X-ray stone shadow disappeared after treatment. Indications for GAT include ductal stones around 1 cm in transverse diameter, extensive intrahepatic stones and postoperative residual stones. The mechanism of stone expulsion by GAT is discussed on the basis of both clinical and laboratory studies. Factors that may influence clinical GAT results are also discussed.

The long-term results of a local-made dacron prosthesis in replacement of the thoracic aorta are presented. Of the 36 patients treated by this method, the early and late mortalities of operative resection and grafting were 11.1% and 19.5%. The longest follow-up period was 14 years. Most of the survivors are in excellent condition.
