Embodiment 1

[0019] Example 1: Effect of Soybean Protein Isolate on Adriamycin Myocardial Injury in Mice

[0020] (1) Animal modeling

[0021] Fifty male Kunming mice of SPF grade, weighing 18-22 g, were selected and divided into 20 normal control groups (group A), 24 model groups (group B), and 26 soybean protein isolate groups (group C). Animals in groups A and B were fed with common feed; animals in group C were fed with soybean protein isolate (Hubei Yunmeng Longyun Protein Food Co., Ltd., batch number: 20120321-5) mixed with normal feed at a ratio of 1:5. Animals in group A were intraperitoneally injected with normal saline 0.09 ml / 10 g body weight, mice in groups B and C were intraperitoneally injected with 18 mg / kg (0.09 ml / 10 g body weight) of adriamycin (Zhejiang Hisun Pharmaceutical Co., Ltd., batch number 15006911 ), observed for 8 days.

Embodiment 2

[0041] Example 2: Effects of Soybean Protein Isolate on Body Weight, Serum Modified Albumin and Total Sulfhydryl in Adriamycin Myocardial Injury Mice

[0042] (1) Animal modeling and group administration

[0043] Eighteen male Kunming mice, weighing 18-22 g, were randomly divided into three groups: normal control group (group A), intraperitoneally injected with normal saline (0.09 ml / 10 g body weight), and fed normally; model control group (group A) Group B) Adriamycin injection was injected intraperitoneally at a dose of 18 mg / kg (0.09 ml / 10 g body weight) and fed normally; Adriamycin injection was injected intraperitoneally, and fed with 20% high-protein feed.

[0044] (2) Observation indicators

[0045] The body weight changes of the mice in each group were recorded every day, and the serum was collected on the third day of the experiment to detect the levels of total sulfhydryl groups and ischemic modified albumin.

Abstract

The invention discloses application of isolated soybean protein in prevention or treatment of cardiotoxicity caused by an anthracycline antineoplastic drug and is intended to solve the problem that ananthracycline medicine easily produces toxic and side effects in an organism during malignant tumor treatment. The isolated soybean protein is extracted from natural plants and has the characteristics of good safety and environmental friendliness. In an animal experiment, the survival rate of animals can be effectively improved, heart weight can be effectively improved, cardiac muscle fiber breakage can be effectively reduced, inflammatory infiltration is alleviated, ischemia modified albumin level in mouse serum can be effectively lowered, and the total sulfhydryl level of the mouse serum can be effectively improved. The isolated soybean protein is low in cost and beneficial to clinical popularization and application and provides a new thought and new solution for a method used for treating the cardiotoxicity caused by the anthracycline antineoplastic drug.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of drug toxicity, in particular to the application of a soybean protein isolate in the prevention or treatment of myocardial toxicity caused by anthracycline antitumor drugs. Background technique [0002] Anthracyclines include adriamycin, daunorubicin, aclarubicin, epirubicin, pirarubicin, idarubicin, and mitoxantrone, among which adriamycin (ADR) is One of the broad-spectrum anti-tumor drugs commonly used clinically has achieved good curative effect in the treatment of malignant tumors, and is widely used in the treatment of solid tumors, leukemia, lymphoma, breast cancer and other tumors. This type of drug has a high affinity to myocardial tissue, and will produce cumulative and dose-dependent myocardial toxicity, which will further develop into irreversible myocardial damage, and eventually lead to congestive heart failure, and the resulting cardiotoxicity may appear after med...
