[A case of trismus at anesthesia induction possibly attributable to traumatic cervical syndrome].

We recently had a 41-year-old male who developed trisms at anesthesia induction, probably due to traumatic cervical syndrome. Preoperatively, this patient had been able to open his mouth sufficiently to an extent of at least three finger breadths in width. However, when anesthesia was induced, his mouth could be manually opened only to an extent of about one finger breadth in width.

Effects of mastication on glucose metabolism in rats, with emphasis on differences in properties of food consumed whilst breeding.

Objective: In this study, to elucidate the effects of preferred properties of food that affect the daily masticatory habits on the onset of lifestyle-related disease, we investigated whether groups of rats continuously fed with diet having distinct properties show differences in glucose metabolism.

Design: Thirty-six male Wistar rats aged 4 weeks were divided into two groups; only the pellet type feed was given to one (solid diet group), and the powdered feed to the other (powder diet group). The oral glucose tolerance test (OGTT) was performed to measure glucose metabolism.

[Efficacy of continuous epidural saline infusion in cerebrospinal fluid hypovolemia: report of 5 cases].

We identified the sites of leakage by cisternography in 5 patients with cerebrospinal fluid hypovolemia and treated them by continuous epidural infusion with physiological saline solution. The results showed improvement in symptoms in all 5 patients, and lasting favorable results were obtained in 3 of them. Epidural saline infusion is achieved by inserting an epidural catheter that anesthesiologists routinely use, and the procedure and management are both simple.

[Efficacy of remifentanil in anesthetic management for living-donor renal transplantation].

Background: We used fentanyl and remifentanil in living-donor renal transplantation patients. So, we have compared both drugs in renal function.

Methods: We used the volatile anesthetic sevoflurane as the base in 30 living-donor renal transplantation patients, dividing them into a remifentanil anesthesia group of 15 patients and a fentanyl anesthesia group of 15 patients, and compared their creatinine, BUN, and serum K values before surgery, and 1 day as well as 3 days after surgery.

[Drug eruption during living-donor renal transplantation in which it was difficult to identify the causative drug: a case report].

A 59-year-old man with renal failure given oral medication for the symptoms associated with it had no drug allergies before surgery. The patient received 8 units of FFP for a surgery of gastric tumor. The stomach tumor was benign, and living-donor renal transplantation was performed.

[Prospective study on anesthesia for lumbar spine surgery--the effectiveness of the perioperative epidural anesthesia with buprenorphine].

We prospectively evaluated the efficacy of perioperative epidural buprenorphine for lumbar spinal surgery under general anesthesia. Twenty-eight patients were allocated into two groups; in one group (buprenorphine group), patients underwent the surgery under general anesthesia with perioperative epidural buprenorphine 0.2 mg, in the other group (control group), patients underwent the surgery under general anesthesia only.

[Anesthetic management of a patient with mitochondrial encephalomyopathy for renal transplantation].

A 52-year-old man with mitochondorial encephalomyopathy was scheduled for renal transplantation from a living donor. He had some characteristic features including muscle weakness, deafness, cerebellar ataxia, diabetes meritus and renal failure. Anesthesia was induced with bolus infusion of propofol 1 mg x kg(-1) and continuous infusion of remifentanil at 0.

Type 2 diabetes impairs implant osseointegration capacity in rats.

Purpose: The effect of type 2 diabetes mellitus (adult-onset non-insulin-dependent), which is the most common form of diabetes in humans, on osseointegration capacity has not been addressed in an appropriate animal model. This study histologically and histomorphometrically examines bone healing around titanium implants in the type 2 diabetes rat model.

Materials And Methods: Titanium implants with a chamber were placed into the femurs of normal male rats and genetically modified male rats with a close symptomatic resemblance to human type 2 diabetes, as characterized by late-onset hyperglycemia and obesity.

[Propofol does not induce retrograde amnesia at the hypnotic dose].

Background: We evaluated retrograde amnesic effects of propofol at the hypnotic dose on 28 healthy medical personnel volunteers (17 men, 11 women).

Methods: Explicit memory function was measured after the emergence from bolus infusion of propofol 2 mg x kg(-1); how one could answer the correct number and symbol of 5 playing cards which he had picked up randomly and intentionally memorized before induction? As control, one also took the same test during working hour without any drugs.

Results: After infusion of propofol, the rate of correct answers was 96.

Evaluation of the light intensity of high intensity light units.

Purpose: To determine the intensity of PAC (plasma arc curing) light compared with conventional QTH (Quartz tungsten halogen) light using a hardness test.

Methods: The spectral distribution of two light sources was analyzed with a spectroradiometer, after the light intensity was determined. AP-X composite was packed into a black mold (4 mm in diameter and 4 mm in depth) to prepare a cylindrical specimen.

[Prolonged respiratory depression after fentanyl administration in a patient with mitochondrial encephalomyopathy].

A 21-year-old man with mitochondrial encephalomyopathy underwent surgery for removal of a maxillary cyst. During the induction of anesthesia, the patient fell into the state of apnea after intravenous administration of fentanyl 100 microgram. Trachea was successfully intubated followed by propofol 50 mg without any muscle relaxants.

Identification and characterization of two phage-type RNA polymerase cDNAs in the moss Physcomitrella patens: implication of recent evolution of nuclear-encoded RNA polymerase of plastids in plants.

We isolated two cDNAs for the genes PpRPOT1 and PpRPOT2 that encode phage-type RNA polymerases (RPOTs) from Physcomitrella patens. Transcriptional activity of the encoded proteins was demonstrated by an in vitro transcription assay. Transiently expressed RPOT green fluorescent protein fusion proteins were both targeted to mitochondria.
