[Higher lint percent and drought tolerant cotton line selected by radiation breeding].

The Gossypium hirsutum cv. Liaomian No. 9 were mutagenized by 60Co gamma ray, from which the mutant line Zhonghuzhi PI 935 (be called "PI 935" for short) was bred by family selection method. The PI 935 not only has some good traits (growing period, drought tolerance, lint color and fiber quality) similar to the original cultivar, but also has higher lint outturn and lint yield than that of the Liaomian No. 9. The PI 935 has been identified and regional tested in nine places times for four years in the southern Xinjiang Weiwuer autonomous region. It was shown that the PI 935 had the higher lint outtrn for the average 47.3% was ten-point percentage more than that of the check cultivars (Junmian No. 1 or Xinluzhong No. 5), the similar lint yield by and large and the growing period by five days later than that of the checks. The PI 935 was collected in the National Bank of Crop Germplasm (unified No. ZM 114274 and named "Zhonghuzhi PI 935").

Phase II study of hepatic arterial floxuridine, leucovorin, and dexamethasone for unresectable liver metastases from colorectal carcinoma.

PURPOSE: To determine the toxicity, response rate, and survival of a regimen of hepatic arterial floxuridine (FUDR) with leucovorin (LV) and dexamethasone (Dec) for the treatment of unresectable hepatic metastases from colorectal carcinoma. PATIENTS AND METHODS: Sixty-two patients with hepatic metastases (33 previously untreated with chemotherapy) were treated with FUDR (0.30 mg/kg/d) and LV (15 mg/m2/d) and Dec (20 mg total dose) as a 14-day hepatic arterial infusion via an implantable pump alternating with 2 weeks of saline. RESULTS: The complete response (CR) plus partial response (PR) rate was 78% in previously untreated patients, with a median survival duration of 24.8 months; 1- and 2-year survival rates were 91% and 57%, respectively. In the previously treated group, the response rate was 52%, with a median survival duration of 13.5 months. Only 3% of patients (two of 62) developed biliary sclerosis; this was significantly lower than the 21% biliary sclerosis rate observed in our previous trial of hepatic arterial FUDR and LV without Dec (P = .002). CONCLUSION: The addition of Dec to hepatic arterial FUDR and LV reduces biliary toxicity while maintaining an excellent response rate and survival. We recommend that this treatment be studied further.

Rhodotorula septicemia: report of a case.

With the increased use of central venous catheters in cancer patients, there has been an increase in the recovery of environmental and skin organisms from blood cultures. A red yeast, Rhodotorula, an infrequent cause of infection in humans, was isolated from a patient with acute myeloblastic leukemia undergoing bone marrow transplant while he received parenteral nutritional fluids by an indwelling catheter. The patient was clinically ill, as manifested by fever and chills. The patient was treated with amphotericin B and the catheter was removed. He survived the fungemic episode with no recurrence of fungal infection.

New concepts in severe presacral hemorrhage during proctectomy.

In the past, surgeons thought that severe presacral hemorrhage during proctectomy was caused by damage of the presacral venous plexus. By studying the anatomy and clinical data, we found that injury of the sacral basivertebral vein also caused this serious complication. Presacral hemorrhage is seen as massive bleeding from the distal pelvic surface of sacrum or from one to several large-caliber foramina of sacral basivertebral veins in that area. This type of presacral hemorrhage is more dangerous than that from simple injury of presacral venous plexus and sometimes it is fatal. We describe the anatomic features of the vertebral venous system and its close relationship with severe presacral hemorrhage. We also propose some new concepts about cause, hemostatic measures, and principles of prevention.
