Excretion of immunoglobulins in Burkitt's lymphoma.

IgM was detected in the urines of 4 out of 17 patients with Burkitt's lymphoma. This IgM emerged from Sephadex G 200 column in two different peaks strongly suggesting sub-units of the intact molecule. IgM was not detected in any of the control urines. The total protein excreted in the urine of Burkitt's lymphoma patients is higher than in controls and may be due to renal involvement. Intact IgA and IgG as well as fragments of IgG were present in the urines of all Burkitt patients as well as in controls. Six of 16 Burkitt's lymphoma patients had reduced serum levels of IgG. Four of these also had reduced serum IgM. The low mean concentration of serum IgM confirms our previous studies.

Immunoglobulins in Jamaicans and Nigerians with immunogenetic typing of myeloma and lymphoma in Jamaicans.

Serum IgG concentration was lower in Jamaicans than in Nigerians. The maternalfoetal IgG ratio was also lower in Jamaican sera than in Nigerian sera. It is suggested that endemic malaria in Nigeria may be responsible for these differences. The higher IgM concentration in the Nigerian cord sera may be further evidence of this. Eighteen new cases of myeloma were detected in Jamaicans between August 1966 and May 1967. Based on Gm typing, only two of these showed evidence of mixed white ancestry. All the others had the typical Gm groups of Negroes. Similarly, only two patients out of a total of 17 with malignant lymphoma showed evidence of mixed white ancestry. Twelve of the patients with myeloma showed serum proteins of the IgG type, five were IgA, and one had only light chains in the serum. The majority of the patients had myeloma protein of the kappa type. The Gm typing suggested that six patients had myeloma protein of the gamma1 heavy chain subclass, and one patient had a gamma3 subclass heavy chain, the remainder belonging most likely to the gamma2 heavy chain subclass since gamma2 occurs about four times as frequently as gamma4.

Plasma amino-acids in the Nigerian nutritional ataxic neuropathy.

Investigation of nine patients with tropical ataxic neuropathy showed an absence or diminution of sulphur-containing amino-acids-cysteine and methionine-and a variable concentration of most other essential amino-acids. The pattern was unlike that found in kwashiorkor. The levels of serum cholesterol and total protein were normal, and the serum vitamin B(12) levels were normal or high. Plasma thiocyanate concentration was high.All the patients gave a history of a monotonous diet of cassava derivatives. Cassava contains a cyanogenetic glycoside (linamarin) from which cyanide is released on hydrolysis. The excessive cyanide detoxication may be responsible for the low concentration of the sulphur-containing amino-acids.
