Pancreas has two types of cells namely islets of Langerhans and acinar cells. In the early years of research on diabetes, extract of this gland was tested on diabetic patients. Resutls are tabulated below. (i) Extract of pancereas -
(ii) Islet cell extract +
(iii) Acinar cell extract -
The correct interpretation is that

Options

A. anti-diabetic factor in extract'C' was inactivated by extract 'A'
B. anti-diabetic factor present in 'A' was destroyed by 'B'
C. both 'A' and 'C' destoyed the anti=diabetic factor present in 'B'
D. anti diabetic factor present in 'B' was destroyed by

Explanation

To interpret the results from the pancreas extracts tested on diabetic patients, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Pancreas**:
- The pancreas has two types of cells:
- **Islets of Langerhans**: These are endocrine cells that secrete hormones like insulin, which helps to lower blood sugar levels.
- **Acinar Cells**: These are exocrine cells that produce digestive enzymes and do not have a direct role in blood sugar regulation.

2. **Analyze the Results**:
- The results of the extracts are as follows:
- Extract of pancreas: Negative effect on blood sugar levels (ineffective).
- Islet cell extract: Positive effect (effective in reducing blood sugar levels).
- Acinar cell extract: Negative effect (ineffective).

3. **Understand the Implications**:
- The pancreas extract (which contains both islet and acinar cell components) was ineffective in lowering blood sugar. This suggests that the presence of acinar cell factors may inhibit the action of the islet cell factors.
- The islet cell extract alone was effective, indicating that it contains the necessary anti-diabetic factors (like insulin).

4. **Draw Conclusions**:
- Since the acinar cell extract was ineffective and the islet cell extract was effective, it can be concluded that the acinar cells might be producing substances that counteract the effects of the islet cells.
- Therefore, the correct interpretation is that the anti-diabetic factor present in the islet cell extract (B) was destroyed or inhibited by the presence of factors from the acinar cells (A).

5. **Select the Correct Interpretation**:
- Based on the analysis, the correct interpretation of the results is that the anti-diabetic factor present in the islet cell extract (B) was destroyed or inhibited by the acinar cell extract (A).

### Final Answer:
The correct interpretation is that the anti-diabetic factor present in the islet cell extract (B) was destroyed by the acinar cell extract (A).
