Varying reactions of the vegetative nerve system to various point combinations (for example: vomiting, dizziness, diarrhea, urge to urinate, fatigue or drowsiness, headache), especially to the needling of Tai Chong (Li 3), induced us to perform biochemical studies before and after acupuncture treatment. A group of children and a group of adults were studied. The material studied was urine and blood; from the children, urine only. The following were determined in the urine: indolacetic acid, 5-hydroxy-indol-3-acetic acid, homovanillic acid, and vanillic-mandelic acid; in the blood, tyrosine and tryptophan (free and bound). Individual points with wide influence (He Gu = LI 4; Zu San Li = St 36; Tai Chong = Li 3) and their combination with generally effective points were tested. The needling of Tai Chong especially showed a clear increase in indolamine metabolism. Isolated increases in metabolites of catecholamine metabolism could be correlated with the patient's increased physical activity after acupuncture. Noteworthy is the observation that no significant chemical reactions were evident if local reactions to the needling no longer appeared at the end of a series of acupuncture treatments.

The effect of deoxynivalenol (DON, vomitoxin) on brain amine levels was investigated in swine. DON, a trichothecene mycotoxin, causes suppression of feed intake (anorexia) in susceptible species. Following acute administration of DON to pigs (0.25 mg/kg, IV), concentrations of endogenous catecholamines norepinephrine (NE), dopamine (DA), 3,4-dihydroxyphenyl-acetic acid (DOPAC), and homovanillic acid (HVA), and the indoleamines, 5-hydroxytryptamine (5HT, serotonin) and 5-hydroxyindoleacetic acid (5HIAA) were determined in five brain regions, periodically during the 24 h post-dosing. Analysis was carried out by high performance liquid chromatography, using electrochemical detection. Effects of DON in the swine brain were transmitter, time and region-specific. It was observed that levels of the major transmitters (NE, DA and 5HT) were statistically different from controls in the hypothalamus (Hypo), frontal cortex (FCX) and cerebellum (Cb) up to 8 h post-dosing. Overall, DON administration elevated NE and depressed DA concentrations in these regions, and levels of 5HT which increased initially in Hypo (1 h), had dropped significantly below controls in both Hypo and FCX at 8 h. These alterations, however, were not indicative of known neurochemical changes associated with chemical-induced anorexia. Instead, this data suggested that the neurochemical effects of acute DON exposure might be due to peripheral toxicological events (i.e., vomiting), which overwhelmed its more subtle feed refusal activity.

The metabolism of serotonin was studied in cancer patients of their first day of their first course of chemotherapeutic drugs either with strongly or moderately emetogenic regimens. It was observed that strongly emetogenic treatments induce greater increases in serotonin release than moderately emetogenic regimens. High-dose cisplatinum (75 +/- 5 or 83.8 +/- 5 mg m-2) produced a marked increase in the plasma levels and in the urinary excretion of 5-hydroxyindole acetic acid (5-HIAA). Neither platelet nor plasma (platelet-free plasma) serotonin were significantly modified by high-dose cisplatinum. Dacarbazine (283 +/- 22 mg m-2), another strongly emetogenic agent, induced acute nausea and emesis paralleled by marked increases in the urinary excretion of 5-HIAA. Both for high-dose cisplatinum and dacarbazine, the increases in serotonin metabolism occurred with a similar time-course than those of vomiting, and lasted for a period of 4 to 8 h. Low-dose cisplatinum (30.8 +/- 3 mg m-2) as well as cyclophosphamide-based chemotherapies (520 +/- 30 mg m-2) produced very small increases in the urinary excretion of 5-HIAA. Platelet and plasma serotonin levels failed to increase in cyclophosphamide-treated patients. Octreotide, a long-acting somatostatin analog, did not inhibit the increase in urinary 5-HIAA and the nausea and vomiting produced by high-dose cisplatinum. These results suggest that for treatments that induce marked increases in serotonin release such as high-dose cisplatinum or dacarbazine: (a) the amount and time course of serotonin release induced by chemotherapeutic drugs determines the severity, time of onset and pattern of emesis observed; (b) platelet serotonin play no role in chemotherapy-induced emesis; (c) strongly emetogenic regimens release serotonin from enterochromaffin cells; and (d) intestinal release of serotonin is the consequence of the damage induced by the chemotherapeutic drugs on the gut mucosa.

Possible local and systemic adverse effects following administration of salmon (sCT) and human (hCT) calcitonin (CT) have been evaluated in a double-blind, within-subject, comparative trial in 30 young, healthy volunteers. Each subject received 0.25 and 0.5 mg hCT and 100 IU sCT s.c.. Adverse effects and hypocalcaemia were recorded 1, 3 and 6 h after each injection. Significantly fewer local adverse reactions were observed after hCT (20 or 33%) than after sCT (80%), possibly due to the different vehicles employed (mannitol solution and acetic acid). The most frequent systemic adverse effects were gastrointestinal (nausea, vomiting), which occurred in 80% after 1 h, independently of the CT--preparation used. Hypocalcaemic changes were generally small and lasted longer after sCT. It is concluded that the hCT preparations were better tolerated locally than sCT in young, healthy volunteers, and that there were no differences in the systemic side effects or hypocalcaemic activity.

To evaluate the anticancer agent flavone acetic acid (FAA), we conducted a Phase I trial involving 17 pediatric patients with various malignant solid tumors. Dosages investigated included 5,120 and 6,144 mg/m2 given as 3-hour intravenous infusions; and 10,000, 12,500, 15,000, and 17,500 mg/m2 delivered in a 24-hour constant infusion with alkalinization. Grade 2 or worse toxicity was minimal, with 2 patients having nausea/vomiting, 2 having diarrhea, 1 becoming hypertensive, 1 becoming hypotensive, and 2 having myalgia. Three patients who received a 17,500 mg/m2 dose had no toxicity. Disease was stabilized for a brief period in 2 patients--1 with brain stem glioma and 1 with astrocytoma. The FAA pharmacokinetics varied with an average (SD) terminal half-life of 27.9 hr (18.7), clearance of 2.04 L/hr/m2 (0.37), and steady-state volume of 19.9 L/m2 (10.6). This study was discontinued because FAA caused no significant toxicity or therapeutic responses at doses 2.5 gm/m2 greater than had been tolerated by adults.

Effects of acetate and bicarbonate dialysates on tolerance to dialysis have been examined in 30 patients with chronic renal failure (CRF). Symptomatic homeostatic impairment (nausea, vomiting, headache) and cardiovascular instability (tachycardia, arrhythmia, dyspnea) were less common (p less than 0.05) in bicarbonate dialysis. The cardiovascular symptoms correlated with antihypertensive effects of acetate (p = +0.48). Tolerance to ultrafiltration was better with bicarbonate dialysis. Gas chromatographic measurement of blood acetate concentrations in 7 patients on bicarbonate dialysis showed them to be 1.4 +/- 0.31 mmol/l at the beginning of dialysis treatment and 1.7 +/- 0.24 mmol/l at its end (normal, 1.7 +/- 0.14 mmol/l). Of 26 patients on acetate dialysis, 9 patients showed initial and late acetate concentrations of 1.7 +/- 0.26 and 2.5 +/- 0.23 mmol/l, respectively, while in 17 patients an initial concentration of 4.8 +/- 0.32 mmol/l rose to 9.0 +/- 1.1 mmol/l at the end of the treatment (p less than less than 0.01). Dialysis-induced complications had a higher incidence in the latter group (p less than 0.02). Acetate dialysis was poorly tolerated by 65% of the patients. The intolerance was aggravated by myocardial lesions and slow acetate turnover indicated by blood acetate concentrations above 7-8 mmol/l.

Grayanotoxin-III (GTX-III) is a constituent in leaves of Pieris japonica D. Don which exhibits, in vitro, the ability to open voltage-sensitive sodium channels in various excitable tissues. Effects of systemic administration of GTX-III were studied in vivo using Std-ddy mice. Salivation, vomiting and paralysis of the hind paws invariably occurred in mice injected intraperitoneally with 0.1 or 0.25 mg/kg of GTX-III. The writhing response to an intraperitoneal injection of acetic acid was considerably diminished by pretreatment of animals with the toxin. The grayanoid also caused a profound attenuation of the response to caudal compression, while inducing no significant alteration of that to thermal injury. Pretreatment with GTX-III resulted in a significant decrement of the time required for loss of the righting reflex induced by pentobarbital, with a concomitant delay in recovery. Mice injected with the toxin exhibited a significant and restorable suppression of coordination, and a long-lasting suppression of spontaneous locomotor activity in both horizontal and vertical directions. Neither tetrodotoxin (1-5 micrograms/kg, i.p.) nor Ro15-1788 (1-5 mg/kg, i.p.) prevented the GTX-III-induced suppression of locomotion. Atropine (5-10 mg/kg, i.p.) failed to antagonize the GTX-III-induced suppression but protected against salivation induced by the toxin without affecting other symptoms. Intracerebroventricular injection of quisqualic acid (0.5 microgram), one of the agonists for central glutamate receptors, but not that of tetrodotoxin (5 ng) prevented the GTX-III-induced suppression of horizontal movement. These results suggest that GTX-III may elicit its depressant action on horizontal locomotion possibly through interacting with central glutamatergic neurons rather than activating voltage-sensitive sodium channels in the brain. Possible involvement of muscarinic cholinergic neurons in the GTX-III-induced salivation is also suggested.

The effects of repeated oral administration of cefuroxime axetil were assessed in Beagles. The test material, an ester, is hydrolysed following absorption from the intestine to yield the therapeutically active moiety, cefuroxime, together with acetic acid and acetaldehyde; in this study cefuroxime and unhydrolyzed cefuroxime axetil were detected in the blood. Cefuroxime axetil was administered twice daily during 27 weeks by gavage of aqueous, suspensions, total daily doses were equivalent to 100, 400 or 1600 mg cefuroxime/kg/day. Apart from three cases of intercurrent illness, unrelated to treatment, the dogs remained in good health. Effects observed in the 1600 mg/kg group included vomiting and slight suppression of body weight gain. Minor variations in haematological measurements included rather low haemoglobin levels, packed cell volumes and erythrocyte counts. Slightly smaller numbers of neutrophils were thought to reflect reduced demand on normal defensive mechanisms due to continued antibiotic treatment. Prolongation of prothrombin time and activated partial thromboplastin time is attributed to disturbance of the intestinal microbial flora and reduced synthesis of vitamin K, on which the dog is highly dependent. Cefuroxime does not have the N-methylthiotetrazole side chain thought to be responsible for inhibition by other cephalosporins of the vitamin K-dependent step in the synthesis of clotting factors. Variations in plasma chemistry included rather low levels of plasma protein. Electrophoresis showed this to be a generalised reduction; only gamma globulins were proportionally decreased and this finding, like the low neutrophil counts, is attributed to the protective action of the antibiotic. Minor metabolic adjustments to the compound are reflected in plasma levels of cholesterol and triglycerides. This spectrum of findings was seen only to a very limited extent in the 400 mg/kg group; the 100 mg/kg group was, with very few exceptions, unaffected by the treatment. Macroscopic post mortem examination and microscopic examination of tissues revealed no treatment-related features indicative of toxicity. Cefuroxime axetil was thus shown to possess very little toxicity when administered repeatedly in large doses to Beagles. The lowest dose level in this study was ten times the proposed daily clinical dose in man.

Antipyretic effect, tolerability, and acceptance of alpha-methyl-4-(2-thienylcarbonyl)-phenyl acetic acid (suprofen, Suprol) suppositories were tested in an open study including 90 hospitalized children with fever of various etiology. The mean rectal temperature prior to treatment was 39.3 degrees C. The dose regimen was chosen depending upon the body weight: Up to 4 suppositories were administered for maximally 4 days. Body temperature as well as pulse and respiratory rates were recorded prior to insertion of the suppository and 0.5, 1, 1.5, 2, 3, 4, 5 and 6 h following first application of the preparation. Regardless of sex and age the temperature was reduced in 85.5% of the cases; as compared to the initial values this reduction was after first application statistically significant at all rating times. The only adverse reaction - vomiting - was seen in 3 cases.

The antipyretic effect of single doses of alpha-methyl-4-(2-thienylcarbonyl)-phenyl acetic acid (suprofen, Suprol) syrup, administered at dose levels of 1, 2, 3, 4, 5, 7.5, and 10 mg/kg b.w., was tested in a randomized double-blind and a subsequent open study. The test populations consisted of 100 children in the double-blind study and 40 patients in the open test (20 subjects/group). The patients' age ranged from 2 to 12 years; the lowest initial rectal temperature was 39.0 degrees C. The treatment groups were homogeneous as to demographic data. The temperature was reduced in all treatment groups. In the double-blind study the mean value dropped under the subfebrile threshold of 38.0 degrees C only in the group on 5 mg/kg and remained then constant for up to 6 h following administration. No sufficient antipyretic effect was obtained with lower doses. The results of the additional open study with doses of 7.5 and 10 mg/kg indicated good antipyretic effect. This effect was not, however, superior to that obtained with 5 mg/kg. Pulse and respiratory rates returned to normal within 1.5 h following administration, except in patients on 1 mg/kg. A total of 10 patients, homogeneously distributed in the treatment groups, experienced vomiting as an adverse reaction. Short-term hypotonia was seen in one subject on 7.5 mg/kg. The results obtained show that single doses of suprofen upward of 5 mg/kg b.w. exert satisfactory, long-lasting, antipyretic effect on children.
