1-Azacycloalkyl-1,4-benzodiazepin-2-ones with antianxiety-antidepressant actions.

A series of 1-azacycloalkyl-1,4-benzodiazepin-2-ones were synthesized from 1-azacycloalkyl-2-benzoylanilines and corresponding imines and then evaluated for their central nervous system activities. Pharmacological data showed that some of these compounds have potent antidepressant properties, as assessed by their antagonism of tetrabenzine (TBZ) induced ptosis and their inhibition of [3H]norepinephrine uptake into rat brain synaptosomes, as well as their moderate antianxiety properties of preventing of pentylenetetrazol (PTZ) convulsion, suppressing conflict behavior, and displacing potential for [3H]diazepam binding. Introduction of a halogen substituent at position 7 of the 1,4-benzodiazepine ring lengthened the anti-PTZ effects, although the peak effect was slightly reduced and clearly enhanced the anti-PTZ and anticonflict properties. Introduction of Cl to the ortho position of the phenyl ring at position 5 greatly reduced the antidepressant properties. The secondary amine function of the azacyclic ring at position 1 was essential for the production of the antidepressant properties. Of these new series, 7-fluoro-5-(2-fluorophenyl)-1,3-dihydro-1-(4-piperidinyl)-2H-1,4-benzodi azepin-2 -one has the potential to become a useful antidepressant drug with a moderate antianxiety property.

[Two cases of giant vesical diverticulum in females].

Two rare cases of giant vesical diverticulum without infravesical obstruction in female are presented. The first case, a 58-year-old female, was admitted because of diverticulum with continuous urinary infection, which was diagnosed by urological examinations for hematuria. The second case, a 58-year-old female, was admitted with the diagnosis of diverticulum, which was done by the gynecologist during laparotomy for the suspicion of a right ovarian cyst. Neither patient complained of difficulty in urination in spite of remarkable residual urine and no neurologic abnormalities were detected. The cystograms of the two cases revealed over-goose-egg sized diverticula and vesical capacity was over 800 ml, in both cases. The other urograms and endoscopy showed no evidence of vesical trabeculation or any obstructive changes of bladder neck or urethra in either case. Therefore, mucosal diverticulectomy in the first and total diverticulectomy in the second, was performed for the residual urine. Each surgical specimen showed the muscle layer of the walls. In the post-operative course, urination was improved in spite of the underactive detrusor pattern of the cystometry in the first case. But residual urine volume was not decreased after the operation in the second case. These two cases seem to be congenital vesical diverticulum. But it is hard to rule out the possibility of secondary diverticulum due to neurogenic disorders of urinary bladder.

[Evaluation of neurogenic bladder in patients with spinal cord injury using a CMG.EMG study and CMG.UFM.EMG study].

Simultaneous recording of intravesical pressure, sphincter electromyography and uroflowmetry (CMG.UFM.EMG study) was performed following cystometry simultaneously with electromyography (CMG.EMG study) on 20 patients with spinal cord injuries. Differences in the influence to micturition between the CMG.EMG study and CMG.UFM.EMG study is thought to be due to whether the catheter is indwelling in the urethra or not. We examined those differences and patient's rehabilitation maneuver (Cred'e maneuver). Micturition pressure and opening pressure measured by the CMG.EMG study were larger than that measured by the CMG.UFM.EMG study (P less than 0.05, P less than 0.01 respectively). Incidence of detrusor-sphincter dyssynergia measured by the CMG.EMG study was greater than that measured by the CMG.UFM.EMG study in the detrusor hyperreflexic cases. The Cred'e maneuver caused increase in opening pressure, micturition pressure and peak flow rate, but the voiding volume and voiding time did not increase to any effective extent. The Cred'e maneuver exaggerated the detrusor sphincter dyssynergia.

[Double primary malignant neoplasm of renal cell carcinoma and stomach cancer: report of two cases].

Two cases of double primary malignant neoplasm of renal cell carcinoma and gastric cancer are presented. Case 1 was a 59-year-old woman with right renal cell carcinoma (granular cell subtype) and gastric cancer (poorly differentiated adenocarcinoma). Case 2 was a 72-year-old man with left renal cell carcinoma (clear cell carcinoma) and gastric cancer (tubular adenocarcinoma). In both cases, the occult blood reactions of stool was strong and clear gastrointestinal symptoms developed. In these 2 cases of synchronous double cancer, gastrectomy following nephrectomy was performed in the same operation.
