A genetic analysis of the hyperthermic response to d-amphetamine in two inbred strains of mice

A genetic analysis of amphetamine-induced hyperthermia was conducted in inbred mice of the strains Balb/c and C₃H and in their F₁F₂ and backcross generations. The results of biometric analysis indicate that the effect of amphetamine on body temperature is genetically determined. The mode of inheritance characterized by a partial dominance (Balb/C over C₃H strain). However, a possible matermal effect of C₃H can overcome the dominant effect in male progenies and inhibit amphetamine hyperthermic effect.     

Effects of adenosine 3′, 5′-cyclic monophosphate on thermoregulation in both rats and rabbits

Summary The effects of intraventricular administration of dibutyryl adenosine 3, 5-cyclic monophosphate (db cyclic AMP) on the thermoregulatory responses of unanesthetized rats and rabbits to different ambient temperatures (T_a) were assessed. Administration of db cyclic AMP (10–60 mM) produced dose-dependent hypothermia in both rats and rabbits at T_a 2–22 °C. The hypothermia in response to db cyclic AMP was due to decreased metabolic heat production and cutaneous vasodilatation. There was no change in respiratory evaporative heat loss. In contrast, in the heat (30–32 °C), db cyclic AMP administration produced dose-dependent hyperthermia in these animals. The hyperthermia was due to increased metabolism (due to muscular shivering) and decreased heat losses. The reduction in heat losses was shown by a decrease in both cutaneous circulation and respiratory evaporative heat loss. The data demonstrate that the thermoregulatory responses induced by central administration of db cyclic AMP are T_a-dependent.

Phase I study of combined radiation, hyperthermia and intra-arterial carboplatin for local recurrence of cervical cancer.

BACKGROUND: Patients with cervical cancer who develop pelvic recurrence after primary surgery are usually treated with radiation-based therapy. However, their prognoses are dismal. We conducted a phase I study of combined radiation, hyperthermia and intra-arterial (IA) carboplatin for local recurrence of cervical cancer. PATIENTS AND METHODS: Patients with local recurrence of cervical cancer without extrapelvic recurrence were included in this study. Carboplatin was given as a 5-min IA infusion without hydration just before pelvic radiation every day. External pelvic irradiation (1.8 Gy/day for 28 days) was performed according to local standard schedules. After 20 Gy had been administered, hyperthermia was performed once a week with a radio frequency heating system for four cycles. RESULTS: Fifteen patients were entered through the four dose levels of carboplatin. The maximum tolerated dose was determined to be 25 mg/m(2 )and the dose-limiting toxicities were leukocytopenia, neutrocytopenia and diarrhea. Grade 3/4 leukocytopenia and diarrhea were observed in nine (60%) and three (20%) of 15 patients. Tumor responses included five complete responses and nine partial responses, and the overall response rate was 93.3% (14 of 15) (95% confidence interval 59.4% to 100%). Tumor reductions were observed only at 20 Gy in 10 cases of 14 responders (71.4%). CONCLUSION: The combination therapy of radiation, hyperthermia and IA carboplatin is safe and well-tolerated for locally recurrent cervical cancer.
