1390 free heparin (1000 units per ml.) and diluted tenfold in culture-medium RPMI 1640 containing 100 units of penicillin and 50 (1.g. of streptomycin per ml., and tritiated leucine (specific activity 54 Ci per mmol) at a concentration of 0-5 mCi per ml. This suspension was dispensed in triplicate 3 ml. aliquots to upright tissue-culture tubes 16 x 125 mm. containing various dilutions of purified P.H.A. The tubes were cultured with and without autologous serum, or calf serum, for 22 hours. Then the cells were centrifuged and washed twice with 3% acetic acid, bleached with one drop of 30% hydrogen peroxide, heated at 85 °C for 20 minutes, and dissolved in 0-6 ml. of NCS solubiliser, resuspended in scintillation fluid, and counted for 10 minutes on a Hewlett Packard scintillation counter. The results (figs. 1 and 2) confirm that there is a conspicuous depression of cell-mediated immunity in disseminated neoplasia and show a definite, though less striking, depression in patients with glioma. The apparent depression of cell-mediated immunity in patients with benign intracranial tumour is not significant. In our preliminary study the effect of autologous serum on protein synthesis was not clearly and defined, a more detailed analysis with a larger group of patients would be necessary to elucidate this point. These results show that there is a definite impairment Of P.H.A. responsiveness in lymphocytes of patients with malignant glioma. The impairment of protein synthesis in these lymphocytes may be due to an intrinsic abnormality or to a humoral inhibiting factor in the serum. Further work on analysing this immune defect is in progress and may have important implications for management of intracranial tumour.

APHTHOUS ULCERATION, CROMOGLYCIC ACID, AND CELLULAR IMMUNE RESPONSE

SIR,-It has been reported that disodium cromoglycate (D.S.C.G.), a known inhibitor of IgE-mediated release of histamine1 and other substances in type-i immune reactions, conveyed in toothpaste, reduces the incidence of recurrent aphthous ulceration.’ In a double-blind trial of cromoglycic acid, the acid form of D.s.c.G., in topical tablet form, we found a significant reduction in the symptoms but not the incidence of recurrent aphthous ulcers.3 In view of the proposal that cell-mediated reactions may play a part in the pathogenesis of aphthous ulceration4 and of the effects of levamisole (a drug thought to modify the cellular immune response) upon aphthous ulceration,5 we determined the effect of D.S.C.G. upon in-vitro lymphocyte responsiveness.6 D.S.C.G. at 100 and 1000 µg. per ml. did not alter the in-vitro lymphocyte response of 6 individuals to a mitogen, P.H.A., and an antigen, P.P.D., as measured by lymphocyte transformation, production of -macrophage migration inhibitory factor, and lymphotoxin production. Both of these concentrations of D.S.C.G. were apparently non-toxic for the lymphocytes in culture. It seems possible that the c.G.A. in the trial was acting upon a second immune component of the ulceration, one giving rise to the pain in the middle of the ulcer life. This second immune phase may be associated with the reduction in the demonstrable 1. Assem, E. S. K., McAllen, M. M. Br. med. J. 1970, ii, 504. 2. Frost, M. Lancet, 1973, ii, 389. 3. Dolby, A.

Obituary HERBERT VICTOR MORLOCK

M.C., M.D.Lond., F.R.C.P.

Dr H. V. Morlock, consulting physician to the London Chest Hospital and the Miller and Hampstead General Hospitals, died on May 18 at the age of 76. In the 1914-18 war, immediately after leaving school, he joined the Rifle Brigade, saw service in France, and was decorated with the M.c. on the field at the age of 19. He qualified M.B. from St. Bartholomew’s Hospital in 1924, and was elected to the staff of the first of his three hospitals at the age of 28. With the late Dr A. J. Scott Pinchin he spent some months in Vienna and on his return started the bronchoscopy clinic at the London Chest Hospital, using an instrument of his own design with a telescope for direct vision. This pioneer work, in which he was later joined by E. H. Hudson, established diagnostic bronchoscopy firmly in the hands of chest physicians and thoracic surgeons and was complementary to the work of H. P. Nelson on postural drainage for bronchiectasis. Some found his dynamic personality a little forbidding, but those who accepted this soon developed for him an admiration coupled with affection. There was about him an endearing streak of eccentricity. He habitually wore the old-fashioned style of dress of a consultant after most others had abandoned it, entirely in keeping with his basic philosophy that whatever you set out to do should be done properly. A story runs that at the beginning of the 1939-45 war patriotism impelled him to give up his Rolls and take to an Austin Seven, only to find that he could not sit in it with his top hat on unless the sunshine roof was open. The war affected him keenly; the arrival of the N.H.S. in 1948 even more so. Feeling that his initiative would be cramped, he withdrew to some extent. When he retired he transferred his boundless energy to riding and the hunting field. We shall cherish the memory of a man of character, a generous, warm-hearted colleague. He is survived by his wife, a son, and a daughter who is herself a doctor.

His early surgical career was interrupted by service with the R.A.M.C. in the 1939-45 war; he landed in Normandy on D + and was involved in the Arnhem campaign. In civilian life, some years as consulting surgeon to Mercer’s Hospital were followed by appointment to the staff of the Royal City of Dublin Hospital and of the Rotunda and Drumcondra Hospitals. He held the chair of surgery at the Royal College of Surgeons of Ireland and later became regius professor of surgery at Trinity College, Dublin. Failing health led to his retirement in 1972. He was a skilful, dedicated surgeon and teacher who will be deeply mourned by friends, colleagues, and patients throughout Ireland. His first wife died in 1950, leaving him with two daughters and a son. He is survived by his second wife, whom he married in 1959.

Mary Frances Appleby, formerly director of MIND (National Association for Mental Health). DISCOVERING SOCIAL PATHOLOGY

WHEN Dr Tonge and his colleagues1 began to look at problem families in Sheffield they were interested in the psychiatric aspects. However, their experiences forced on them a broader outlook: " We became more interested in the social pathology which could not be ascribed to psychiatric disorder ... " Thirty-three families living in Corporation housing in south-east Sheffield were selected from the lists held by various social agencies such as the children’s department and the family service unit; all the families were in touch with three or more agencies or with two agencies one of which was engaged in intensive casework. Neighbouring families matched for maternal age served as controls. A lot of the detail in the ensuing thorough study is unsurprising: the problem families, by definition, had many problems. As a social study the material is rather too selective; the families in question constituted only 0-17% of those in a working-class area and almost certainly represented the extreme end of a broad spectrum of families in difficulty. The problems, in the words of Tonge and his colleagues, form an " interlocking mosaic ", but the remedies, they believe, must be
