本文报告了潮阳县地方性氟中毒的流行范围、强度和流行因素。全县有地氟病区78个,分布于13个镇62个乡。其中重病区21个,中病区23个,轻病区34个,病区总人口238410人,占全县总人口13.4%。长期饮用高氟深层地下水和温泉水是地氟病发病的主要原因。病区均属水型病区。氟斑牙、氟骨症患病率男女无明显差异,与水氟含量呈等级正相关。氟骨症患病率随年龄增大而增高,病情随水氟含量增高而加重。居住年限越长,发病越多。本文还对本病防治对策进行了讨论。 相似文献

Hui-LAN CHUNG. M. D. 《中华医学杂志(英文版)》1931,49(4):617-643
The successful feeding experiments of different investigators sucli
as Archibald (1), Cornwall and LaFrenais (2), Shortt, Craighead,
Smith, and Swaninath (3, 4) and Khaw (5) have demonstrated beyond
doubt the possibility of oral infection in experimental kala-azar.
These experiments naturally lend support to the hypothesis that
human kala-azar may follow oral infection although further proof is
required to decide whether or not in nature such a mode of infection
is actually important. Human cases of kala-azar contracted by the
oral route have not been reported hitherto. I venture to report the
following suggestive case firstly because it seems of sufficient interest
to put on record, and secondly because I wish to invite more attention
to the question of oral infection. 相似文献

In 30 therapeutically aborted fetuses at the
intrauterine ages of the fourth to eighth month
from an endemic goiter region, the thyroid gland
was examined morphologically. Fetal and ma-
ternal serum T3, T4 and TS.H were assayed. The
results were compared with the data of 20 0ther
therapeutically aborted fetuses of the same in-
trauterine ages from a nonendemic regiom 13
fetal goiter cases from the endemic region group
were studied. The thyroids were markedly
increased in weight and size and showed the
following histologic features: Follicular hyper-
plasia with high cuboidal or columnar epithelia
lining acini containing little or no colloid; cel-
lular hyperplasia with formation of solid cell
masses; prominent hyperemia of perifollicular
capillaries and presence of foci of enlarged fol-
licles distended with colloid. Enlargement of the
thyroid gland occurred early in fetal life. The
cause of fetal goiter in this series was presum-
ably iodine deficiency, as was true for endemic
goiter in the same region. The morphogenesis
of fetal goiter was presumed to be similar to
that of acquired iodine deficiency goiter.
Changes of the thyroid gland are apparently the
result of increased serum TSH, a feedback
stimulation of decreased serum T4 concentra-
tion. The fact that the se'rum TSH was mark-
edly elevated and T+ decreased in the goitrous
fectuses of this series strongly supports this
hypothesis. 相似文献

Gaschen in 1934 reported the presence of P: barraudi (1),
recumbent-haired species from Che-chuan(芷村) in the south of
Yunnan. Since then, no further records have been added to the
sandfly fauna in this province. In 1940 we were ab7e to secure
sandfly specimens from two other localities in this province, namely,
Mangshih(芒市) in the west and Kunming(昆明) in the east. In
the former place a total of 208 sandflies was collected from the early
part of July to the end of October. Of these, 203 were identified to be
P. barraudi (155 ♂, 48♀) and 5 P. siantoni (2 ♂, 3 ♀), an erect-
haired species. This combination of collection shows that P. barraudi
was the predominant species in Mangshih in the period surveyed. In
the latter district, three female specimens consisting of one found in
June and two in July were collected and kindly sent to us by Mr.
T. H. Shen, a former member of the staff of our department, for
identification. Upon examination, all the three insects were found t。
belong to one species, namely, P. chinensis. 相似文献

The close relationship between canine and human kala-azar in
Peiping has been shown in a previous communication (1). If one
accepts the view that tFu: dog is the reservoir host of human kala-azar
in North China, then one would expect to find canine leishmaniasis in
all of the kala-azar villages. It is, therefore, important to determine the
presence or absence of canine leishmaniasis in as many kala-azar
villages as possible. Recently some observations of considerable in-
terest concerning the occurrence of canine leishmaniasis in 3 kala-azar
villages in the suburbs of Peiping have been made and are here
recorded. 相似文献

Christophers (1926) reported three species of Anopheles colIected
by Prof. W. S. Patton from I"aian and Tsinan of Shantung. Hindle
and Feng (1929) made experiments with the anopheline mosquitoes and
malaria in Tsinan and found that both A. (M.) tattoni and A. (AJ
hyrcanus var. sinensis are susceptible to the infection of P. viz)ax but the
former is the more favourable host. Feng (1931) gave some further
observations and records of the Anopheles in other parts of the province.
Apart from the above there seems to be no other investigations of these
insects in Shantung. . 相似文献

Ir] a previous communication (1) it was shown that Chinese
hamsters infected with Leishmania donovani can be cured of the
infection by neostibosan. FolIowing a total dose of 5 t0 7 gm per
kilo body weight, all th~ 6 hamsters wliich had survived the course of
treatment, showed no parasites in smears made from the liver and
spleen either by puncture or at autopsy, and they were all aPParently
cured. However, by emulsifying each spIeen and inoculating this
emulsion into a number of normal hamsters, it was found that only 3
of the 6 apparently cured hamsters were actualN cured, as the spleen
emulsion prepared from 3 0f them was still capable of causing kala-
azar in normaI hamsters. 相似文献

In the previous papers of this series (Winfield 1937, 1937 a, 1937 b)
the general plan of this investigation and the results of studies on the
epidemiology of Ascaris lumbricoides in a rural population have been
presented. It was shown that in spite of unfavorable climatic factors
which tend to hold ascaris in check, conditions within the household of
the rural family are such as to make it possible for fairly heavy infesta-
tions to be built up in a large percentage of the population. It was
cmphasized Lhat direct contamination of the environment and not vege-
tables (Winfield and Yao, 1937) seems to be the critical factor. Since
life habits and sanitary conditions are soffiewhat different in the city
from those characteristic of the country the study of the operation of
these factors under urban conditions may be expected to throw light on
their relative importance. In this paper are presented the results of such
studies. 相似文献
